Step-by-step explanation:
The shaded region is referred to as the Annulus of two concentric circles.
To find the area of the shaded region is to subtract the area of the smaller circle from the area of the larger circle.
Let the radius of the larger circle=R
Let the radius of the smaller circle=r
Area of shaded region
R=11cm, r=3cm
Therefore:
Area of shaded region
