Question

If the area of the circle below is 10 in2 what is the area of the shaded sector (The shaded area is 90 Degrees)

Answer 1

A. 2.5 in^2

Explanation:

Answer 2

A) Area of sector = 2.5 in².

Explanation:

Given : If the area of the circle below is 10 in².

To find : What is the area of the shaded sector .

Solution : We have given that

Area of the circle = 10 in².

Formula of area of circle =
`\pi *r^(2)`.

`\pi *r^(2)` = 10

`r^(2)` =
`(10)/(3.14)`

Area of sector =
`(theta)/(360)`
`\pi *r^(2)`

Plugging the values

Area of sector =
`(90)/(360)`* 10.

Area of sector = 2.5 in².

Therefore, A) Area of sector = 2.5 in².
