Calculate the Radius from the Area of a Circle
Calculate the radius, diameter, and circumference of a circle from its area S.
| Radius of a circle r | |
| Circle Diameter R | |
| Circumference of a Circle L |
| \(\normalsize Circle\\ (1)\ radius:\hspace{45px} r=\sqrt{\large\frac{S}{\pi}}\\ (2)\ diameter:\hspace{40px} R=2r\\ (3)\ circumference:\ L=2\pi r=\pi R\\\) |
