   6 dni temu · How do you find the radius of a circle? There are three circle radius formulas, depending on what number you know: The radius of a circle from the area: if you know the area A, the radius is r = √(A / π). The radius of a circle from circumference: if you know the circumference c, the radius is r = c / (2 × π).

   The formula to find the area of a circle is: Area = pi times the radius squared. The radius is a line that starts at the center of the circle and goes to the edge. If you cut the circle in half, the radius would be the distance from the center to the edge. To find the area, we need to know the radius.
