Question

In the figure find the area of shaded region, if the radius of circle is 7 cm and quadrilateral is a square

Answer 1

Answer:

Step-by-step explanation:

Area of the shaded region = Area of square – Area of sector

Side of the square = 7cm

Radius of the circle = 7cm

Area of the square = side×Side

= 7×7

= 49 cm square

Area of the sector =

Theta/360 × π × r × r

Theta = 90°

90°/360° × 22/7 × 7 × 7

=> 1/4 × 22 × 7

=> 1/2 × 11 × 7

=> 11/2 × 7

=> 77/2

=> 33.5 cm square

Area of the shaded region =

49 –33.5

=> 15.5 cm square
