Hint:
Area of Shaded region = Area of Semicircle with 20cm as radius + 2 × (Area of Semicircle with 7cm as diameter(=3.5cm as radius))
A1 = (π(20)²)/2 = 200π cm²
A2 = (π(7/2)²)/2 = 49π/8 cm²
So, Total area of Shaded region = A1 + 2 × (A2)
= 200π + 2 × (49π/8)
= 200π + 49π/4
= (800π + 49π)/4
= 849π/4 = 666.80 cm²
Taking A1 is the area of big Semicircle (with 20 cm radius)
and A2 is the area of small Semicircle (with 7/2 cm as radius)
Thankyou!!!
