Step-by-step explanation:
Area of the shaded region = area of the circle with radius 7 cm - area of the circle with radius 3 cm----------------(1)
<u>Step 1: Finding the area of the circle with radius 7 cm</u>
Area of the circle A = 
On substituting the value of the radius, we get
Area of the circle A =
Area of the circle A =
square centimetre----------------(2)
<u>Step 2: Finding the area of the circle with radius 3 cm</u>
Area of the circle a = 
On substituting the value of the radius, we get
Area of the circle a = 
Area of the circle a =
square centimetre ----------------(3)
<u>Step 3: Finding the area of the shaded region</u>
Area of the shaded region = 
= 
= 125.664 square centimetre
