Question

Find the area of each circle. Round to the nearest tenth.

Step-by-Step Solution

Answer

The area of the circle is $78.5 {\mathrm{in}}^2$.

Step 1. Given information.

In the figure, the radius of the circle is 5 inches.

Step 2. Concept used.

The area of a circle with radius r is given by $A=\pi r^2$.

Step 3. Calculations.

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

Thus, the area of the circle is $78.5\mathrm{in}{.}^2$.
