13 is a number: numbers have no dimensions and so no diameter.
The radius is half of the diameter. So if it is 13 cm, the diameter must be 26 cm.
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
The area of a circle with a diameter of 13 centimeters is: 132.7 cm2
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
The radius is half of the diameter. So if it is 13 cm, the diameter must be 26 cm.
Diameter = 13/3.1416 inches = 4.14 inches (approx)
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 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.
The area of a circle, if it has a diameter of 13 feet, is: 132.7 square feet.
Diameter of circle: 13/pi = 4 mm rounded to the nearest integer
Diameter of circle: 13/pi = 4.138 ft to 3 decimal places
Circumference = (pi) x (diameter) = 13 pi = 40.84 ft(rounded)
Circumference = (pi) x (diameter) = 13 pi = 40.841 feet(rounded)
