Question

From a circular card sheet of radius 14 cm, a square of 4 cm is removed as shown in the adjoining figure. Find the area of the remaining sheet (π = 22/7).

Answer 1

Area of remaining sheet = Area of sheet – Area of square

= πr² – 4² 

= 22/7 x 14 x 14 – 16
[∵ r = 14 cm]

= 22 x 2 x 14 – 16

= 616 – 16

= 600 sq. cm
