Question
Find the area of a sector of a circle having radius $r$ and central angle $\theta$. Express answersto the nearest tenth. $$r=30.0 \mathrm{ft}, \theta=\frac{\pi}{2} \text { radians }$$
Step 1
The formula is given by $\frac{1}{2}r^{2}\theta$, where $r$ is the radius of the circle and $\theta$ is the central angle in radians. Show more…
