From a
circular card sheet of radius 14 cm, two circles of radius 3.5 cm and
a rectangle of length 3 cm and breadth 1 cm are removed (as shown in
the following figure). Find the area of the remaining sheet. (Takeπ
)
Area of
bigger circle =
=
616 cm2
Area of 2
small circles = 2 × πr2
= 77 cm2
Area of rectangle = Length × Breadth = 3 × 1 = 3 cm2
Remaining area of sheet = 616 − 77 − 3 = 536 cm2
