I found that we still do not have a calculator that would calculate the radius of that circle based on the entered area of the circle.

As you know, the area of a circle is calculated by the following formula:

S=\pi R^2

Accordingly, the formula for finding the radius from the area is:

R=\sqrt{\frac{S}{\pi}}

The calculator below uses this formula to calculate the radius. Please note that the units of measurement are not present - this is because the units you use to define the result's units. For example, if 10,582 is square kilometers, then the answer is 58,038 kilometers. If 10582 is square miles - then the answer is 58.038 miles.
