The area of a circle with radius r is calculated using the formula below.
A=Ï€ r^2
We know that the area of the circle is 89 ft^2. By substituting 89 for A in the formula, we can calculate r.
The radius of the circle is a measurement and therefore cannot be negative. Rounded to the nearest hundredth, the radius of the circle is approximately 5.32 feet.
