Introduction

When dealing with geometric shapes, particularly circles, it's essential to understand the relationships between their various properties. One such property is the area of a circle, which is given by the formula $A = \pi r^2$ , where $A$ is the area and $r$ is the radius. In this article, we will explore how to simplify the expression for the radius of a circle with a given area.

The Given Area and Its Implications

The area of the circle is given as 60 square centimeters. Using the formula for the area of a circle, we can set up the equation $\pi r^2 = 60$ . To find the radius, we need to isolate $r$ by taking the square root of both sides of the equation. This gives us $r = \sqrt{\frac{60}{\pi}}$ centimeters.
