The area of a circle with a 13 ft diameter is: 132.7 square feet.
The radius is half of the diameter. So if it is 13 cm, the diameter must be 26 cm.
Well, area of a circle is (pi)r^2 and your diameter is 13, so your radius is 13/2 so your area would be (pi)(13/2)^2 or 132.7322896 =] -ray

The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.

The diameter of any circle is twice its radius. A circle with a radius of 13 inches will have 2 x 13 = 26 inches for a diameter.
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Area = pi*6.52 = 132.732 square feet to 3 decimal places
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
Diameter of circle: 13/pi = 4 mm rounded to the nearest integer
Area = Pi(d/2)2 = Pi*6.52 = approximately 132.73 inches2
The circumference of a circle is Pi times the diameter. Pi = 3.1416 so 3.1416 x 13 = 40.84
