Diameter = radius * 2 Circumference = pi * diameter.
Diameter = circumference/pi Radius = circumference/2*pi
Circumference of a circle = 2*pi*radius or diameter*pi
Using the Circumference And Area.
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
Diameter = radius * 2 Circumference = pi * diameter.
The circumference of a circle with a radius of 3.2 cm is approximately 20.1 cm. This can be calculated using the formula: circumference = 2 * π * radius.
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
Diameter = circumference/pi Radius = circumference/2*pi
The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.
Circumference of a circle = 2*pi*radius or diameter*pi
Using the Circumference And Area.
circumference of a circle = pi*diameter or 2*pi*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
The circumference C of any circle is equal to pi*diameter. The diameter is equal to the radius times 2. So, for a circle with radius 48, it has a diameter of 96, and a circumference of 96*3.14=301.44. This of course is using 3.14 as an estimate for pi.
