If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
If the circumference is 3.14:Diameter = 1Radius = 0.5
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
Circumference = 2*pi*Radius Diameter = 2*Radius Circumference = pi*Diameter
Divide the diameter by 2, this will give you the radius. multiply the radius by the radius, this gives you the radius squared. Multiply the raduis squared by Pi (3.14) to get the circumference. Formula : Circumfrence = Pi X R squared so, if the diameter is 10, the radius is 5, the radius squared is 25, 25 X 3.14= circumference
Diameter = radius * 2 Circumference = pi * diameter.
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = circumference/pi Radius = circumference/2*pi
Radius is the distance from the center point to the edge of the circle. Diameter is the distance straight through the center point and across the circle. Circumference is the distance one full turn around the circle. Radius = 1/2 of the diameter Radius = (circumference) divided by (2 pi) Diameter = 2 times the radius Diameter = (circumference) divided by (pi) Circumference = (pi) times the diameter Circumference = (2 pi) times the radius
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
If you know the circumference, the ration of the diameter to the circumference is π, so diameter = circumference/π If you have the radius, diameter = 2 x radius
circumference: Pi(3.14) x radius squared Diameter: radius squared radius: diameter divided by 2
If you know the radius, then Diameter = 2 x (radius) Circumference = (pi) x (diameter) or Circumference = 2 x (pi) x (radius)
π is the ratio between the diameter and the circumference of a circle so the formula would be : Circumference = π x Diameter or alternatively (since the radius is half the diameter) Circumference = 2π x Radius.
