The area of a circle is found by multiplying the square of the radius by pi.
The area of a 25 foot diameter circle is approximately 491 square feet (12.5 x 12.5 x 3.1416).
490.87
A 25-foot radius circle is 1,963.5 ft2
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
(25×25)×3.14 = 1962.50 ft²
A 13-foot circle has an area of 132.73 square feet.
A 16-foot circle has an area of 201.06 square feet.
The square foot area of a 41-foot diameter circle is: 1,320 square feet.
A circle with a 27-foot diameter has an area of 572.56 square feet.
Approx 490.9 sq feet.
Area of circle: pi*5^2 = 25*pi square feet
452.4 square feet.
