The rule for the circumference of a circle is:
C = 2piR, where R is the radius.
So if the circumference (C) is 12, then:
12pi = 2piR
Divide both sides by 2:
6pi = piR
Divide both sides by pi,
R = 6

The approximate radius is five (5) inches.
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
Well, darling, if a circle has a circumference of 24 inches, we can use the formula C = 2πr to find the radius. Just plug in 24 for C and solve for r. You'll find that the radius of this sassy circle is 3.82 inches.
Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
A circle with a radius of 8 inches has a circumference of 50.27 inches.
The radius of a circle with a circumference of 232.4 inches is 37 inches.
Well, isn't that a happy little question! To find the radius of a circle when you know the circumference, you can use the formula: circumference = 2πr. So, if the circumference is 28.26 inches, you can plug that in and solve for the radius. Just divide the circumference by 2π (which is about 6.28) to find the radius. Happy calculating!
Circumference = 2 x pi x radius = 31.4159
The approximate radius is five (5) inches.
To find the radius of a circle with a circumference of 20 inches, you can use the formula for circumference: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 20 inches, you can plug this value into the formula: 20 = 2πr. Solving for r, you get r = 20 / (2π) ≈ 3.183 inches. Therefore, the radius of the circle is approximately 3.183 inches.
radius = 20/(2*pi) = 3.183098862 inches
The circumference of a circle that has a radius of 5 inches is 10 X pi or approximatly 31.415926535897932384626433832795. If you know the radius you can find the circumference by multiplying it by 2(pi)
C = 25.13 inches.
c = 22"
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.
That will depend on the length of the radius which has not been given but in general the circumference of a circle = 2*pi*radius or diameter*pi
