When blown up, a beach ball has a radius of 12inch. How much air in cubic feet is needed to blow it up. The formula is V=%284%2F3%29%2A%28pi%29%2Ar%5E3
12 in = 1 ft, so your radius is 1 ft.
V=%284%2F3%29%2A%28pi%29%281ft%29%5E3
V=%284%2F3%29%2A%28pi%29%2A%281ft%5E3%29
V=%284%2F3%29%2A%28pi%29ft%5E3
V=%284%2F3%29%283.14%29ft%5E3
highlight%28V=4.18879ft%5E3%29 Round off to where ever your teacher wants you to.
Happy Calculating!!!
