Question

Find the area of shaded region qno b​

Answer 1

21.43cm²

Explanation:

First of all find the area both of semi circles

area of one semi circle = ПΓ²

2

therefore area of both semicircle = ΠΓ²=3.14×5²=78.57cm² (1)

{ ∵Π=3.14 and Γ=5cm }

And the area of square=side ×side=10cm×10cm=100cm² (2)

the area of shaded portion=100-78.57 = 21.43cm² (2)-(1)
