Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi
c=TT R Given the area, the radius = square root (area / Pi). Given the circumference, the radius = circumf/ 2Pi.
Circumfrence=diameter X 3.14 (diameter=2 X radius)
The radius is 1/2 of the circumference.
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
Diameter = circumference/pi Radius = circumference/2*pi
Divide the circumference by 2PI to find the radius. ( C = 2PI*Radius)
Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)
The circumference is 25.1
2 * pi * radius
circumference = 2 x π x radius ⇒ radius = circumference ÷ (2 x π) Divide the circumference by two times π (≈ 6.283).
6 37.68/(2 x pi)
For any given circle, the circumference is equal to the radius multiplied by 2 x pi.
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
Circumference = diameter*pi
