Chapter 0.8, Problem 10E

To determine

To calculate: The area of the figure given.

Answer to Problem 10E

The area of the circle is $\text{78}\text{.5 in}{\text{.}}^{\text{2}}$ .

Explanation of Solution

Given information:

The figure given in the question.

Formula used:

Area $\left(A\right)$ of a circle with radius r is given by $A=\pi r^2$ .

Calculation:

In the figure the radius of circle is 5 inches.

Recall that area $\left(A\right)$ of a circle with radius r is given by $A=\pi r^2$ .

Apply it,

  $\begin{array}{c}A=\pi r^2\\ =3.14\times 5^2\\ =3.14\times 25\\ =78.5\end{array}$

Thus, the area of the circle is $\text{78}\text{.5 in}{\text{.}}^{\text{2}}$ .
