Question

The diameter of a table tennis ball is 40 millimeters.What is the approximate volume of the table tennis ball?

Answer 1

The volume of a sphere is

`V=(4)/(3)\pi(r)^3`

Since the tennis ball is shaped like a sphere, then we will use the rule above to find its volume

Since its radius is 40 mm, then

r = 40 mm

`\begin{gathered} V=(4)/(3)\pi(40)^3 \\ V=268082.5731 \end{gathered}`

The volume of the table tennis ball is about 268082.57 mm^3
