Circumference = 2 * pi * radius 12 pi ft = 2 pi radius radius of the circle = 6 ft Area = pi *radius2 Area = pi (6)2 Area = 36 pi ft2

Area of a circle = pi*radius squared

Area of a circle = pi*radius squared

what is the approximate area of a circle with a radius of 26ft

Approximate area of a 15 foot radius circle is a little more than 700 square feet.

The area is 441 times pi.

r = 34.83 ft C = 218.9 ft

r = 5.597 ft C = 35.16 ft

r = 9.027 ft C = 56.72 ft

r = 5.585 ft C = 35.09 ft

r = 19.54 ft C = 122.8 ft

If you meant: How does one measure the area of a circle in Sqft, The formula is: Pi x Radius in Ft squared. i.e. Area of circle in SqFt. =(22/7) x Radius in Ft x Radius in Ft.

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.

A circle with a radius of 30 feet has an area of 2,827.43 square feet.

A circle with a radius of 4.3 feet has an area of 58.09 square feet.
