Answer:

100π square inches

Explanation:

The area of a circle is given by ...

A = πr^2

where r is the radius. The radius of a circle is half the diameter, so your circle with 20 inch diameter has a radius of 10 inches. Putting that value into the formula gives an area of ...

A = π·(10 in)^2 = 100π in^2

The area is 100π square inches.
