Question

A horse is tied to a pole in a park with a string 21 m long . Find the area over which the horse can graze.​

Answer 1

Since the horse is tied to a pole, the pole becomes the center of circle and the length of string becomes the radius.

Radius (r)=21m

Area where horse can graze = Area of a circle

                                                =πr

Answer 2

Answer:

Since the horse is tied to a pole, the pole becomes the center of circle and the length of string becomes the radius.

Radius (r)=21m

Area where horse can graze = Area of a circle

                                                =πr2

                                                =722​×21×21

                                                =22×3×21

                                                =1386m2
