Question

When purchased, a plastic beach ball is deflated and packaged flat. The package states that when inflated to its maximum capacity, the radius of the inflated ball is 8.5 inches. To the nearest cubic inch, how much air will occupy the space contained by the inflated beach ball? Use 3.14 to approximate . In your final answer, include your calculations.

Answer 1

So  the formula for a volume of a sphere is 4/3 times pi times the radius cubed.
step one: 4/3 times 3.14 = 4.18666666667
Step two: then you cube 8.5 and get 592.45
the final answer is 2,480.3906
