Question

The surface area of a beach ball is 144π in2. Find the volume of air the beach ball will hold when it is fully inflated.

Answer 1

The surface area of a sphere is given by
\[A=4 (pi)r ^{2}\]'The volume of a sphere is given by
\[V = \left( 4\over 3\right)(pi)r ^{3}\]

Answer 2

Solve the first equation for r and plug into the 2nd equation.
