Question

From a circular sheet of radius is 18cm, two circle of radii for 4.5cm and a rectangle of length and breadth 1cm are removed. Find the area of the remain sheet

Answer 1

Step-by-step explanation:

Radius=14 cm

Total area= Tr²=22/7*196=616 cm²

r2= 3.5 cm

Area of the small circles= 2*tr2=2*12.25*22/7=77 cm2

Length of rectangle=3

Breadth=1

Area =Lb=3 cm²

Area of the small circles+area of rectangle=77+3=80 cm²

Remaining area=616-80-536 cm²
