Question

complete the steps, which describe how to find the area of the shaded portion of the circle. 1. find the area of the sector by multiplying the area of the circle by the ratio of the to 360. 2. subtract the area of the triangle from the area of the sector. length of the radius length of the diameter measure of the central angle circumference of the circle

Explanation:

The formula for the area of a sector of a circle is $A=\frac{\theta}{360}\times\pi r^{2}$, where $\theta$ is the measure of the central - angle. So, to find the area of the sector, we multiply the area of the circle by the ratio of the measure of the central angle to 360.

Answer:

measure of the central angle
