Question

Geometry
Find the area of the shaded region

Answer 1

Area = 1125mi

Explanation:

Area of sector =
`r^2 *(\alpha )/(2)`

`r^(2) =5^(2) =25`

`25*(\alpha)/(2)`

`25*(90)/(2) =25*45=1125`

`\alpha` = angle

`r` = radius

radius is 5mi

in this case the angle is 90°

A = 1125mi

you can also solve by using circle area which is
`\pi r^(2)`

then divide by 4 because this is 1/4 of the circle.

Hope this helps
