The area is 5,024 ft2.

The formula for finding the area of a circle is:

A = pi * r2

A for area.

The r is for the radius.

A = 3.14 * 40 ft2

A = 3.14 * 160 ft2

A = 5,024 ft2

The circumference of a circle is 62.8 feet What is the radius of the circle in feet and find the area of the circle?

The circumference of a circle is pi * the diameter. The diameter is radius * 2. The area of a circle is pi * the radius squared. So for a circle of circumference 62.8 ft, the radius is 62.8/pi/2 which is 10.0 ft to 1 decimal place The area is pi * radius squared = 314.2 sq ft.
