382 in³
The basketball is spherical in shape and it's approximate volume (V) can be calculated using the formula
V = [tex]\frac{4}{3}[/tex]πr³ ( where r is the radius )
here the diameter = 9 ⇒ r = [tex]\frac{9}{2}[/tex] = 4.5
V = [tex]\frac{4}{3}[/tex]π × 4.5³
= [tex]\frac{4}{3}[/tex]π × 91.125 = 381.7 ≈ 382 in³
