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 = diameter*pi
Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius
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
Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.
Circumference is pi * diameter, or pi * 2 * radius, so if you are given circumference, then radius = circumference / 2 / pi. Pi is approximately 3.1416 Radius is from the center to the edge. Diameter is twice that (from one edge, through the center to the other edge). Radius = Diameter / 2, so if you're given Diameter, then just divide by 2.
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
To find the radius of a circle with a given circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 26 inches, you can plug this value into the formula and solve for the radius. Dividing the circumference by 2π gives you the radius of the circle, which in this case is approximately 4.14 inches.
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
divide 3.14 by circumference and d=2r
Circumfrence=diameter X 3.14 (diameter=2 X radius)
