Question

A horse is tied to a pole with 28 m long string. Find the area where the horse can graze (take r =22/7).

Answer 1

The string to which the horse is tied can be considered as the Radius.

Radius (or) string = 28 m

(As we know that the area enclosed in a circle is given by the formula πr²)

⇒the area by the horse can graze when tied a string 28 metres long is πr²

Substituting in the formula we get →

                                          AREA = πr²

                                                     = (22/7) × (28²)

                                                     = (22/7) × (784)

                                                     = (22 × 112)

                                                      = 2464 sq. m
