Question

from a circular sheet of radius 5 cm a circle of radius 2 cm is cut off. find the area of the remaining sheet. take π = 3.14​

Answer 1

Answer:

66 cm².

Step-by-step explanation:

Area of circle = 22/7 (r²)

Take r = 5 cm

Therefore area = 22/7 (5²)

= 78.57

Now take r = 2 cm

Therefore area = 22/7 (2²)

= 12.57

Therefore, the area of the remaining sheet = 78.57-12.57=66cm².
