Diameter = radius * 2 Circumference = pi * diameter.
Diameter = circumference/pi Radius = circumference/2*pi
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
Divide circumference by pi, that gives diameter. Radius is half of diameter
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
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
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)
Circumference = Diameter multiplied by Pi Diameter = Circumference divided by pi Radius = Diameter divided by 2.
Circumference = 2*pi*Radius Diameter = 2*Radius Circumference = pi*Diameter
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
Divide circumference by pi, that gives diameter. Radius is half of diameter
Circumference = (pi) x (diameter) Diameter = 2 x radius
