what is the equation for circumference and for volume?

anonymous · Answer

C = pi times D & volume = 4/3 pi r ^2

anonymous · Answer

okay, so the circumference you would divide by pi to get D, right? however since volume uses r. we would divide D then by 2 so you get the radius and can find the volume :)

150.72 in ^3 is that right? @Hope_nicole

anonymous · Answer

for what?

anonymous · Answer

nevermind I got it. But is this false or true??

anonymous · Answer

i would say false.

anonymous · Answer

a sphere is 3 demensional, thats just a circle when assembled.

anonymous · Answer

Alrightt thank you. How can I find the radius? @Hope_nicole

anonymous · Answer

well the volume is 4/3 pi r^2, so i would first divide by pi. then divide by 4/3 and then square root it so get just r.

are you sure your volume formula is right?
