13 pi or ~40in
Circumference = (pi) x (diameter) = 13 pi = 40.841 feet(rounded)
The circumference of a 13 inch round circle is: about 40.84 inches.To do this calculation for other circles, just multiply the diameter by Pi (about 3.1416). The result is the circumference.
The formula for the circumference (C) of a circle is C = 2πr where r is the radius. But, the diameter (D) of a circle is twice the radius so this formula can be written C = πD. C = π x 13 = 40.841 cm (3dp)
You can get the circumference of a circle using either the equation radius times 2 times Pi or diameter times Piand im guessing by wide you mean diameter.So 13 x 3.14 (Pi)3.14x 13------9423140-------4082then add the decimal40.82so 40.82 ft is your answer
81.7 cm
circumference = pi * diameterC = 3.14 * 13 = 40.82 inches
Circumference = 13*pi inches or 2*pi*6.5 inches
Circumference = 2*pi*rr(radius) = diameter/2 = 13 in/2 = 6.5 inch radiusCircumference = 2*pi(6.5 inches)= 41 inches in circumference===================
Diameter of circle: 13/pi = 4.138 inches rounded to 3 decimal places
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
The circumference is about 40.84 units.
The circumference of a circle is Pi times the diameter. Pi = 3.1416 so 3.1416 x 13 = 40.84
Circumference = pi*13 yards
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 13-foot diameter circle is: ~40.84 ft
Diameter = 13/3.1416 inches = 4.14 inches (approx)
Circumference = (pi) x (diameter) = 13 pi = 40.841 feet(rounded)
