How do you find an radius of a circle?

How do you find the radius of a circle?

1. Radius of a circle from area: if you know the area A , the radius is r = √(A / π) .
2. Radius of a circle from circumference: if you know the circumference c , the radius is r = c / (2 * π) .
3. Radius of a circle from diameter: if you know the diameter d , the radius is r = d / 2 .

What is circumference of 20cm?

Hence, Circumference and Area of Circle are 62.8 cm and 314 cm².

What is radius in circumference of a circle?

To find the radius from the circumference of a circle, you have to do the following: Divide the circumference by π, or 3.14 for an estimation. The result is the circle’s diameter. Divide the diameter by 2. There you go, you found the circle’s radius.

What is radius and diameter of circle?

When we connect a point on the circumference of a circle to the exact centre, then the line segment made is called the radius of the ring. The distance between the center of the circle to its circumference is the radius. The diameter is always double the radius.

How do I find the radius of a circle from the area?

To find the radius, divide the area by pi, then take the square root.
