Chapter 11.3, Problem 16PPS

To determine

To calculate: The radius of the circle.

Answer to Problem 16PPS

The radius of the circle is $5.97in$ .

Explanation of Solution

Given information: The area of the circle is $112i{n}^2$ .

Calculation:

From the given information, Area, $A=112i{n}^2$ ft.

Area of a circle is given by, $A=\pi r^2$

  $A=\pi r^2$ ,

  $r$ is the radius of the circle.

  $\begin{array}{l}112=\pi \times r^2\\ r^2=\frac{112}{\pi }\\ r=5.97in\end{array}$

The radius of the circle is $5.97in$ .
