Question

a horse is tied to a pole with 21 m long string find the area where the horse can graze​

Answer 1

Answer:

            Area of circle = pi * r * r

                                     = (22/7) * 21 * 21

                                     = 1386 m^2.

Answer 2

Length of the string = 21m.

Therefore area of grass that the horse can graze =${ πr}^2 =π × 21m × 21m. =(22/7 ×21 × 21){m}^2 1386{m}^2$
