Question

I need to know the answer to the question with the circle

Answer 1

___________________________

◆ AREA RELATED TO CIRCLES ◆ ___________________________

As shown in the figure ,

Radius of circle = 5 cm

Side of square = 2 × (Radius of inscribed circle)

Side of square = 2 × 5 cm

Side of square = 10 cm = a

___________________________

Now ,
Area of shaded region = (Area of square) - ( Area of inscribed circle )

Area of shaded region =

`{a}^(2) - \pi {r}^(2)`

Area of shaded region =

`{10}^(2) - (22)/(7) * {5}^(2)`

Area of shaded region = 100 - 78.571


`= 21.428 \: ans.`
