Chiquita and The Rhonda are each building a snowman. Rhonda tells Chiquita that she is making each of her 3 balls of snow 20% smaller than the one below it. Rhonda starts by making the base ball with a diameter of 20 inches. If she reduces the diameter by 20% each time she makes a new ball, what is the diameter of the third ball she makes (the ball for the snowman's head)? Express your answer as a decimal to the nearest tenth.

10.2 inches

Step-by-step explanation:

The initial diameter of the base ball is 20 inches

Reducing this diameter by 20% means; (100-20)/100 * 20

80/100 *20 =16 inches

Reducing this diameter by 20% for the second time gives

80/100* 16 = 12.8 inches

Reducing this for the third time gives;

80/100 * 12.8 =10.24 inches
