A rubber ball has a diameter of three inches. What is its volume? a. 14 in3
b. 4.2 in3
c. 1.4 in3
d. 42 in3

Diameter of the ball = 8 inches

Radius of the ball (r) = diameter ÷ 2 = 8 ÷ 2 = 4 inches

π = 3.14

Surface area of the ball (A) is the same as the surface area for a sphere = 4 π r² = 4 × 3.14 × 4² = 200.96 inches²
