Step-by-step explanation:
Area of shaded region=area of the bigger circle -area of the smaller circle.
Let's take the radius of small circle as r
Bigger circle's radius as R
Then,Pi*R*R-Pi*r*r=ar of shaded region
3.14×20×20-3.14×8×8=ar of SR
1256-200.9=1055.1
Therefore,the area of the shaded region is 1055.1 sqcm

The area of the shaded region = (22/7)*{(20*20)-(8*8)] cm^2
= (22/7)*(400-64) cm^2
= (22*336/7) cm^2
= (22*48) cm^2
= 1056 cm^2
