Type the radius of the circle and press Enter:

The diameter of a circle is a straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It is the longest chord of the circle and is equal to twice the radius.

The formula to calculate the diameter of a circle is:

d = 2r

where d is the diameter and r is the radius of the circle.

To find the diameter of a circle, you need to measure the distance across the circle passing through its center, or you can use the formula mentioned above if you know the radius.

For example, if a circle has a radius of 5 cm, the diameter can be found as:

d = 2 × r d = 2 × 5 cm d = 10 cm

So the diameter of the circle is 10 cm.

Similarly, if you are given the diameter of a circle and need to find the radius, you can use the following formula:

r = d/2

For instance, if a circle has a diameter of 12 cm, then the radius can be calculated as:

r = d/2 r = 12 cm/2 r = 6 cm

Therefore, the radius of the circle is 6 cm.
