Chapter 11.3, Problem 13PPS

To determine

To calculate: The area of the circle.

Answer to Problem 13PPS

The area of the circle is $78.5f{t}^2$ .

Explanation of Solution

Given information: The diameter of the circle is $10ft$ .

Calculation:

From the given information, diameter, $d=10ft$ .

Therefore radius,

  $\begin{array}{l}r=\frac{d}{2}=\frac{10}{2}\\ r=5ft\end{array}$

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

  $\begin{array}{l}A=\pi \times 5^2\\ A=3.141\times 25\\ A=78.52\end{array}$

Area, $A=78.5f{t}^2$

The area of the circle is $78.5f{t}^2$ .
