How to find the radius of a circle with the circumference?

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


How do you find the radius of a circle is you have the circumference?

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


How do you find the radius of a circle only knowing the circumference?

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.


How do you find the area of a circle without knowing 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.


How do you find a diameter of a circle?

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)


How do you find diameter when you have the radius?

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


How do you find out the circumference from the diameter?
