Question

If the area of the circle shown below is 12 m2, what is the area of the shaded sector

Answer 1

A

Explanation:

Answer 2

A)
`3 m^(2)`

Explanation:

We are given the area of the circle = 12
`m^(2)`

The central angle and the arc length = 90°

Therefore, the shaded region is quarter circle. Which is quarter of the whole circle.

So, we can find the shaded sector area dividing 12 by 4.

Area of the shaded sector =
`(12)/(4)`

=
`3 m^(2)`

Therefore, the answer is A)
`3 m^(2)`
