Question
A sector of a circle has a central angle of $60^{\circ} .$ Find the area of the sector if the radius of the circle is 3 $\mathrm{mi} .$
Step 1
The formula for the area of a circle is $A = \pi r^2$, where $r$ is the radius. In this case, the radius is 3 miles, so the area of the entire circle is $A = \pi (3^2) = 9\pi$ square miles. Show more…
