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 [tex]\frac{3}{4} \pi[/tex]r² where r is the radius.

Volume =  [tex]\frac{3}{4} \pi[/tex](7.75)²

             = 45.046875[tex]\pi[/tex]

             = 142 (rounded to 3 s.f.)
