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

The volume of a piece of the cake will be 588.75 cm³.
The complete question is attached below.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
A birthday cake in the shape of the right-circular cylinder of radius 15 cm and thickness 10 cm is cut into smaller pieces.
One of the piece is shown.
Then the volume of piece of the cake will be
V = (30 / 360) x π x 15² × 10
V = 588.75 cm³
