Question
A sector of a circle has a central angle of $45^{\circ} .$ Find the area of the sector if the radius of the circle is $6 \mathrm{~cm}$
Step 1
We know that $\pi$ radians is equal to $180^{\circ}$, so to convert $45^{\circ}$ to radians, we multiply by $\frac{\pi}{180}$: \[45^{\circ} \times \frac{\pi}{180} = \frac{\pi}{4} \text{ radians}\] Show more…
