Question

A largest possible circle is cut out of a square sheet having a side of 6 meter. What is the area of the hollow sheet?

A

36 - 9π sq. m.

B

6 + 18π sq. m.

C

6 + 81π sq. m.

D

36 - 4.5π sq. m.

Soln.
Ans: a

The radius of the circle is 6/2 = 3 m. So its area = π × 3 × 3 = 9π sq. m. The left area is $6^2 - 9$π = $36 - 9$π sq. m.
