Question

A beach ball has a diameter of 10 inches. What is the volume of air contained inside the beach ball? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answer 1

523.33 cubic inches

Explanation:

Answer 2

if the ball's diameter is 10, the radius is half that, or 5 then,


`\bf \textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}\quad \begin{cases} r=radius\\ -----\\ r=5 \end{cases}\implies V=\cfrac{4\pi \cdot 5^3}{3}`
