Question

11. A circle of radius 2 cm is cut out from a square piece of an aluminium sheet of side
6 cm. What is the area of the left over aluminium sheet? (Take T = 3.14)​

Answer 1

Answer:

Radius of circle=2 cm and side of aluminium square sheet=6 cm

According to question,

Area of aluminium sheet left=Total area of aluminium sheet−Area of circle

=side×side−πr2

=6×6−722×2×2

=36−12.56

=23.44cm2.

Therefore, the area of aluminium sheet left is 23.44cm2.
