Solution

The correct option is B


Given that area of the polygon is 24πcm2 .

To find the area of the shaded region, we have to find the area of the circle and remove the area of the polygon from it.

Area of the circle = πr2=π(7)2=49π cm2

So, area of the shaded region = (49π cm224π cm2)=25π cm2
