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 radius is half of the diameter. So if it is 13 cm, the diameter must be 26 cm.
The area of a circle with a diameter of 13 centimeters is: 132.7 cm2
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
The area of a circle with a 13 ft diameter is: 132.7 square feet.
Diameter is twice the radius, therefore the radius is half the diameter. 13/2 = 6.5
Diameter = 13/3.1416 inches = 4.14 inches (approx)

Circumference = (pi) x (diameter) = 13 pi = 40.841 feet(rounded)
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
Diameter of circle: 13/pi = 4 mm rounded to the nearest integer
Circumference = (pi) x (diameter) = 13 pi = 40.84 ft(rounded)
The area of a circle, if it has a diameter of 13 feet, is: 132.7 square feet.
