Three tennis balls just fit into a cylindrical container so that there is no movement of the balls when the lid is closed. Each ball has a diameter of 6.4 cm. Find the volume of each ball

Answer 1

First, filter out the unimportant information. Because the question asks us to find the volume of each ball, and the diameter of each ball is given, none of the other information is important.

To find the volume of a sphere, use the formula V=4πr³/3, with r (radius)=d (diameter)/2.

Hence, the volume of each ball is V = 4π(3.2)³/3 ≈ 137.26cm³.
