Divide circumference by pi, that gives diameter. Radius is half of diameter

pi X diameter finds the circumference so circumference divided by pi will leave the diameter. half the diameter to find the radius

The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.

If the circumference or diameter is given then you can find the radius or simply measure the distance from the centre of the circle to the circumference.

If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)

The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius

circumference of a circle = pi*diameter or 2*pi*radius

Circumference of a circle = 2*pi*radius or diameter*pi

The circumference of a circle is calculated by multiplying the diameter of the circle by Pi. Multiply the radius by 2 to find the diameter. The diameter is 125.6. Now multiply it by Pi. (Pi equals 3.14) This makes the circumference of the circle 394.38.

You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it.

If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.

To find the circumference of a circle you multiply the diameter by pi (3.14), the diameter is two times the radius.

circumference of a circle = 2*pi*radius or pi*diameter

Circle's circumference = 2*pi*radius or diameter*pi

You divide the circumference by Pi (about 3.1416). This gives you the diameter. Divide the diameter by two to get the radius.

If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)

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.

Circumference of a circle = pi*diameter or 2*pi*radius

Radius is diameter divided by two. Diameter is radius times two or circumference divided by pi. Circumference is diameter times pi. Pi is roughly 3.14

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi

circumference of a circle = 2*pi*radius or diameter*pi

Circumference = 2*pi*radius or diameter*pi

The circumference of a circle is 15\piπ m. Find its radius, in meters. The Answer Should Be 7.5

Diameter = Radius*2 = 14 units. Circumference = pi*Diameter = 43.98 units.

Circumference of any circle = 2*radius*pi or diameter*pi

it is the circumference divided by pi which = the diameter. the radius is half the diameter.
