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.
Divide the circumference by pi divided by 2

Whats the radius of a circle with circumference 30 cm?
To find the radius of a circle with a circumference of 30 cm, we can use the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given C = 30 cm, we can plug this value into the formula and solve for r. 30 = 2πr r = 30 / (2π) r ≈ 4.77 cm Therefore, the radius of the circle is approximately 4.77 cm.

If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.

If the circumference of the circle is 75.36 what is the radius?
To find the radius of a circle when given the circumference, you can use the formula: circumference = 2 * π * radius. Given that the circumference is 75.36, you can plug this value into the formula and solve for the radius. First, divide the circumference by 2π to find the radius. The radius of the circle would be 75.36 / (2 * 3.14159) ≈ 12. The radius of the circle is approximately 12 units.
How do you get the radius of a circle from the circumfrance?
To find the radius of a circle when given the circumference, you should start with the formula for circumference, which is this: circumference = 2*pi*radius To solve for the radius, you would the have to divide the circumference by 2*pi leaving you with a formula like this: radius = circumference/(2*pi) pi≈3.14159
