10.2 inches

Step-by-step explanation:

The diameter of the base ball is initially 20 inches.

Reducing 20 inches by 20% will be

(100-20)/100 *20

80/100*20=16 inches

Reducing 16 inches by 20% to will be;

80/100*16=1.6*8=12.8

Reducing 12.8 inches by 20 % will give

80/100* 12.8=10.24 inches

Nearest tenth the answer will be 10.2 inches
