Question

Adult size basketballs have a radius of approximately 12 cm.

Answer 1

Answer:

The volume of air needed is 603 cm³.

Explanation:

In general, basketball has a size of a sphere, so you have to find the volume of sphere using the formula :

$v = \frac{4}{3} \pi {r}^{2}$

$let \: r = 12$

$v = \frac{4}{3} \times \pi \times {12}^{2}$

$v = \frac{4}{3} \times \pi \times 144$

$v = 192\pi$

$v = 603 \: {cm}^{3} (near. \: whole \: no)$
