Find the volume of air in a beach ball has a diameter of 18 centimeter
The beach ball is a sphere......and the volume of a sphere is
(4/3) * pi * (diameter / 2)^3 =
(4/3) * pi * ( 18 / 2)^3 =
(4/3) * pi * ( 9 ) ^3 =
(4 / 3) * pi * (729) =
(729 / 3) * 4 * pi =
243 * 4 * pi ≈ 3053.63 cubic centimeters
