BrandonKeele:

I need help finding the circumference, I have my notes, and all that, but Idk- I'm just slow when it comes to math, I just don't understand it, also my teacher isn't here we have a sub and I kinda forgot how to do it. (IT is NOT a test.) (Ss below)

I need help with 1, Please don't give the answer, I just don't understand how to set it up.

Imagine:

Would you rather have an example or the formula?

Yes please, that'd be much appreciated.

Imagine:

So, both alright, give me a second to put the formula down.

Well just one of them is alright, it;s up to you if you want to do both, Either way it helps and thank you.

Imagine:

$C=2\pi r$ So an Example would be, Say radius=8 |dw:1620838908985:dw| As radius equals 8, you need to divide it by two because you need the half- radius, not the full thing. So, it turns into 4. Because: $8\div2=4$ &/or $8\times0.5=4$ So, when trying to find the circumference, you: $C=2\pi r$ Install the r, as r=4 $C=2\pi (4)$ Now, install that in a calculator; $C=2\pi(4)=25.1$ Now, the question is solved! $C=25.1$ πΈ ππππ ππππ ππππ πππππ πππππππππππ πππ ππππππ ππ πππππ π’πππ ππππ πππππ ππππ π πππ; π²ππππππ ππ ππ π’ππ ππππ πππ’πππππ ππππ... @πΈππππππ

BrandonKeele:

Thank you, This Helps quite a bit.

@imagine radius is already half, it's if you have diameter, you want to cut it in half and find radius So if you had a radius of 8, it would just be 8(pi)(2)

Imagine:

Yeah, I had forgotten the term for a full radius. Thanks Snow.
