Question

Find the area of the shaded sector of the circle show all of your work write your answer in terms of pi

Answer 1

Step-by-step explanation

We are to find the area of the shaded sector

To do s,w e will have to use the formula:

`(\theta)/(360)*\pi r^2`

in our case, the central angle is a major angle

`\begin{gathered} \theta=360-90=270 \\ r=18ft \end{gathered}`

Thus, we will have

`(270)/(360)*\pi*18^2=243*\pi=243\pi`

Thus, the answer is

`243\pi`
