From a circular card sheet of radius 14 cm, a square of 4 cm is remove

1.	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» 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

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»

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
