Question

A horse is tied with a rope in the center of grassland to graze. The length of the rope is 5m. The diameter of the circular garden is 50m. Find the area in which the horse cannot graze.

Answer 1

The length of the rope with which the horse is tied becomes the radius of the circular area.
Length of rope = 5 m
Area within which the horse can graze
= pi * r^2 = 3.14 * 5 = 15.7 m^2
Area of the grassland at the Centre of which the horse is tied = 3.14 * 25
= 78.5 m^2
Area in which the horse cannot graze
= Area of grassland - Area in which the horse can graze
= 78.5 - 15.7
= 61.8 m^2
