Volume of a sphere?

A solid plastic ball is a sphere with radius 4 in. How much plastic does it take to make one ball? Use 3.14 for π.

So the volume of a sphere is 4/3times 3.14 and 4 aqaured

4/3 (3.14) (4*4*4)

4/3*3.14=4.1867

*4cubed which is 64. so 64*4.1867=267.95

so the answer may be close cuase of rounding errorers
