Question

Help! I give medals:)
If a regulation soccer ball has a circumference of 70cm then what are the diameter radius surface area and volume.Show work

Answer 1

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

Answer 2

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

Answer 3

C = 2πr

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

Answer 4

r=63.72??

Answer 5

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

Answer 6

r=11.13

Answer 7

or would u round n r would equal 12 @geerky42

Answer 8

go ahead and use that

Answer 9

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

Answer 10

n diameter is 24?

Answer 11

diameter would be twice the radis

Answer 12

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

Answer 13

i used 12
