Question
Find the area of the sector of a circle of radius $r$ and central angle $\theta .$$r=12$ millimeters, $\theta=\frac{\pi}{4}$
Step 1
Step 1: The formula for the area of a sector of a circle is given by $\frac{1}{2}r^{2}\theta$, where $r$ is the radius and $\theta$ is the radian measure of the central angle. Show more…
