If 88 m wire is required to fence a circular plot of land, then the area of the plot is?

526 m2
556 m2
616 m2
None of these

Correct Answer: 616 m2

Explanation:

Circumference of circular plot= 88 m
⇒ 2 x (22/7) x r = 88
⇒ r = 88 x (7/22) x (1/2) = 14 m
Now area = πr²
=( 22/7) x 14 x 14 m²
= 616 m²
