Chapter 11.4, Problem 44SPR

To determine

To find: The radius of the circle.

Answer to Problem 44SPR

The radius of the circle is $5.5\text{ft}$ .

Explanation of Solution

Given:

The area of the circle is $95{\text{ft}}^2$ .

Calculation:

Consider the area of the circle is of the form,

  $A=\pi r^2$

Then,

  $\begin{array}{l}95{\text{ft}}^2=\pi r^2\\ r^2=\frac{95{\text{ft}}^2}{\pi }\\ r=\sqrt{\frac{95}{\pi }}\\ r=5.5\text{ft}\end{array}$
