Answer:

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

Step-by-step 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 $\frac{3}{4} \pi$ r² where r is the radius.

Volume = $\frac{3}{4} \pi$ (7.75)²

= 45.046875 $\pi$

= 142 (rounded to 3 s.f.)
