@Jim766 @gaara438125 @ChrisNeedsHelp @thomaster  do u think one of u could help me plezz :)

jim766 · Answer

circumference = 2 pi r
70 = 2(3.14) r        solve for r

geerky42 · Answer

C = 2πr

So find radius from circumference then use the value of radius to find surface area $SA = 4\pi r^2$, and volume $V = \dfrac{4}{3}\pi r^3$

anonymous · Answer

r=63.72??

geerky42 · Answer

To find r, divide both sides by 2π or 2(3.14)

anonymous · Answer

r=11.13

anonymous · Answer

or would u round n r would equal 12 @geerky42

jim766 · Answer

go ahead and use that

anonymous · Answer

@Jim766 i get SA=576pi n v=2304pi is that correct?

anonymous · Answer

n diameter is 24?

jim766 · Answer

diameter would be twice the radis

jim766 · Answer

SA = 4(3.14)(11.13)^2= 1555.89

i used 12
