Question

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

Answer 1

Solution

Step 1

Write the area of a circle formula

$\text{Area of a circle = }\pi r^2$

Step 2:

Substitute the value of r = 7 ft

$\begin{gathered} \text{Area of a circle = }\pi\text{ }\times\text{ 7}^2 \\ Area\text{ of a circle = 49}\pi \\ Area\text{ of a circle = 153.9 ft}^2 \end{gathered}$
