My formula for finding a cone is 3.14 × half of diameter squared × height ÷ 3 = answer. (I do this with a calculator, because if I didn't, it'd be wrong) I made up my own formula because I couldn't figure out their formula

Correct ^^

Sometimes it helps if you understand how/why the formula works. I had a GREAT math teacher in high school, and that is how he taught us the various formulas for area, volume, etc.

Half the diameter is the radius. It's used in A LOT of formulas, and called "r." That 3.14 is pi, and anytime you have circles or spheres, you'll have pi involved. (I don't have the letter pi -- it's a Greek letter -- on my keyboard, so I have to spell it out.)

Pi x r squared is the area of the circle that is the base of the cone. Then you multiply by the height, and divide by 3, just like you wrote above. (I don't know why 3. I'm sure Mr. Richardson showed us, but I can't remember.)

Math has a language FULL of abbreviations, so that's why you get stuff that looks like hieroglyphs.

Volume of a pyramid is actually easier than a cone. No circles, no pi, no radius, no squaring. Multiply the width of the base by the length of the base. (That's the area of the base of the pyramid.) Now multiply that by the height. You have the volume of a solid box shape, square or rectangle, it doesn't matter. Divide by 3, because due to some math hocus-pocus, the pyramid is 1/3 the volume of that box. So that's why it's LxWxH/3.

I'm really showing my age, but there was a cartoon called "Pogo." One of the characters said, "Pie are not square! Pie are round! Cornbread are square!" I said that in math class and Mr. Richardson cracked up.

Pi=π. That's what they use, but I want to make certain that I have 3.14 memorized, so I always use it. My school didn't teach me my formula, I figured it up myself. They're always talking about doing something on both sides of a number, which gets super confusing. It sounds like you had a great teacher. I probably would of learned Math better with your teacher than with my animated teachers.

Divide by 3 because you have to divide by 1/3 of the answer. That's probably why. I didn't know this, they just told me to divide by 1/3. I didn't know what they meant, so I googled it and found 0.333... Wrong. I used 3, and started doing better.

I discovered L×W, but when the base had x, v, and k, I didn't know what to do and wouldn't even get a close answer. You are very good at Math! You are writing words that I've never heard of before! Some of your words that you are saying I'd give up with spell check, just trying to figure out how to get it close enough for spell check to figure out what I'm saying! (Yes, I have difficulty with spelling too, but that's what Google, Siri, and Alexa is for. )

I don't know how you're showing your age, I've never heard of that cartoon before. My family loves watching the old, classic Looney Tunes and Pink Panther. (My favorite character has always been Daffy Duck.) Is Pogo older than that?

Here's some of your confusion. Divide by 3 is EXACTLY the same as multiply by 1/3.

If someone says Divide by 3 and someone else says Multiply by 1/3, they are saying the same thing. But if the numbers get mixed up, or they misspeak, or you mishear and you Divide by 1/3, your answer will be way off.

Here's something that it took awhile for me to understand. Dividing is the same as multiplying by "the inverse." <--- huh what??? Take any number, and for instance, we'll pick on 3 again. What is the inverse? 1 divided by 3, or 1/3. WHYYYYYYY? Think of 3 as "3 divided by 1." Invert (turn upside down) the number to get 1 divided by 3.

3/1 inverse: 1/3.

So I want to divide something, and we'll give 3 a break and use 4. 100 divided by 4 = 25. Think of money. $1.00 divided by 4 = 25 cents.

You will get the same answer if you multiply 100 by the inverse of 4, which is 1/4.
100 times 1/4 = 25.

A lot of fractions make weird decimals. 1/3 is nice and neat, but .333333 isn't. 1/4 is nice and neat, and so is .25.

I have read a lot about how different people's brains work differently. In my brain, math is nice and orderly. Not necessarily so in everyone else's brain though! And doctors are just now beginning to figure this out.

Pogo is a newspaper cartoon from the 1950s-60s. I don't think it was ever on TV.

Sorry for rambling on. Hope I didn't derail this thread! Here's a positive thought for everyone in the Northern Hemisphere: The equinox is 5 days away! Spring!

i think your messages were very helpful! they make sense and explain it well

So by the sounds of it, inverse is what they've been talking about in my Math. Once they start talking about that, they lose me. I get all confused and everything. Nothing makes sense. That's why I had created my own formula on figuring up the cones. You are soo super good at Math!!! I wish it was possible that YOU could be my teacher instead of those animated teachers. You make it so much easier to understand!

About the brains, yes, some work differently. My Mom loves studying things like the brain. She often talks about the learning differently. Eggsample: I have a hard time comprehending what I read. So, when a question is handed to me, and I have to read boring instructions first, I can't do it. Whereas my sister, would know it instantly. I remember things better if they are in story form, whereas my sister remembers things better if they're in instruction form.

Ohhhh.... Wait- 1950-1960? Ohhhh... That's what you mean by showing your age. Well, as the Bible says, that grey hair is a crown. The older you get, the wiser you get.

That's ok with me. I don't mind you rambling on. I do it too. Spring? Yay!!!!!

"All the things that hurt you, actually teach you."

Just read that on another thread, and it is very true.

But, oh, some of the lessons are so painful. So, put it away for a while, if you need to have some space for healing. Then later, look at it again, sometimes bit by bit, and see what you can learn from it.

A friend of mine was a victim of sexual assault. She said she loses patience with people who say things like, "Why does God let bad things happen to the people who love Him?" She said, "He gave me the lessons I learned and the strength I gained from a very painful experience." I thought that was a very wise way to see things.

I agree.
Though I feel like someone who's been through sexual assault, or has something horrible happen to them that's caused by someone else, should not feel that they need to learn a 'lesson,' like they had done something wrong. They are innocent, the person who hurt them is the one who needs to learn a lesson! But I do agree that challenges can bring us greater strength and understanding of the world if we let them, (which I think was what you were trying to say anyway).
Anyway, I hope your friend has healed and is doing well. I also hope you are doing well today
