Answer:

4186.67 cubic inches

Step-by-step explanation:

Volume of a sphere = 4/3 π r³

π = 3.14

Diameter = 20 inches

Radius = r = Diameter/2 = 20 inches/2 = 10 inches

Volume of the sphere = 4/3 × 3.14 × (10 inches)³

Volume of the sphere = 12560 ÷ 3

= 4186.6666667 cubic inches

Approximately to the nearest hundredth = 4186.67 cubic inches

Therefore, the volume of the ball is 4186.67 cubic inches.
