Answer: 30pi^2 divided by 2

Step-by-step explanation:

To find the area of a circle, it is pi x radius ^2

Since it is a semicircle 30 is the radius.

pi x radius ^ 2 = 30pi^2

the area would be 30pi^2 divided by 2

Answer:

Answer:

Area of a CIRCLE with radius of 3 inches is

PI * radius^2 =

3.14159265 * 3^2 =

28.27433385 square inches.

Since we are dealing with a SEMI-CIRCLE, we divide that by 2 and get:

14.137166925 square inches which rounds to about

14.14 square inches
