13 pi or ~40in
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.
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
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)
2*pi*radius = circumference 2*pi*radius = 13 Making the radius the subject of the formula is: radius = 13/(2*pi) = 2.06901426 feet Check: 2*pi*2.06901426 = 13 feet
Circumference = pi x diameter = pi x 13 = 40.84 feet or 40'10"
The circumference of a circle with a diameter of 13 mm is: 40.84 mm
Circumference of a circle = diameter x (pi) = 13 pi = 40.841 feet (rounded)
Circumference of a circle is found by multiplying the diameter by pi (for general use pi is 3.14). 13 x 3.14 = 40.82 feet
The radius of a circle with a circumference of 13 feet is: 2.069 feet.
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
Circumference = Pi x d: 3.14 x 13 = 40.82 feet
The circumference of a 13-foot diameter circle is: ~40.84 ft
Circumference = (pi) x (diameter) = 13 pi = 40.84 ft(rounded)
The circumference is about 81.7 feet.
