Use this formula where r is the radius: C = 2Pi(r)
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
The circumference is 25.1
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
circumference of a circle = 2*pi*radius or pi*diameter
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
Easy. First, double the radius to get the diameter. Next, multiply the diameter by Pi (about 3.1416) to determine the circumference.
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
The circumference is 25.1
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
If circumference(C) is given, then r = C/2(pi) If area(A) is given, then r = (A/pi)1/2
If you mean the diameter and radius of a circle given the circumference it is:- diameter = circumference/pi radius = circumference/(2*pi)
The circumference (c) of a circle = 2πr (where r = radius). Therefore if you know the circumference, the radius (r) = c/2π.
circumference of a circle = 2*pi*radius or pi*diameter
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
Circumference refers to the size of something as given by the distance around it, e.g. the circumference of a circle is the distance around it, or its perimeter. The circumference of a circle can be used in the following formula to determine other values in a circle: C=2πr, or C=πd, where C is the circumference of the circle, r is the radius of the circle, d is the diameter of the circle and equivalent to twice the radius, and pi is, well, pi.
Circumference = diameter*pi
