The radius is the circumference divided by 2 x pi.
C= pi(2r)
R=C/2pi
Divide the circumference by Pi (about 3.1416). This gives you the diameter. Now divide the diameter by two to get the radius.

How do you find the radius of a circle when only given the circumference?
Divide the circumference by (2*pi)
What is the radius of a circle of a circumference of 121?
To find the radius of a circle with a circumference of 121, you can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 121, you can plug this value into the formula and solve for the radius. Dividing 121 by 2π will give you the radius of the circle, which is approximately 19.24 units.
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
How do you find the circumference of a circle with a radius of 4?
Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
When you know the circumference of a circle how do you find the diameter?
