Diameter = circumference/pi Radius = circumference/2*pi

If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi

Radius = square root of (area/pi) Circumference = 2*pi*radius

circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) Divide the circumference by two times π (≈ 6.283).

Diameter = circumference/pi Radius = circumference/2*pi

If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)

Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi

divide 3.14 by circumference and d=2r

Divide the circumference by (2*pi)

Radius = square root of (area/pi) Circumference = 2*pi*radius

circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) Divide the circumference by two times π (≈ 6.283).

If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.

Divide the circumference by the value of Pi, then halve that result.

circumference of a circle = 2*pi*radius or pi*diameter

2 pi rthis is the equation of the circumference of a circle. just multiply out 2 times pi(3.14159) times the radius that you were given.
