Answer:

Radius: 7.75; Volume: 142 (rounded to 3 s.f.)

Explanation:

The vollyball is a sphere.

The diameter of a sphere is twice as much as its radius.

Radius = 15.5 ÷ 2

= 7.75

The volume of a sphere is
$(3)/(4) \pi$ r² where r is the radius.

Volume =
$(3)/(4) \pi$ (7.75)²

= 45.046875
$\pi$

= 142 (rounded to 3 s.f.)
