Question

A horse tied to a pole fixed at one corner of a 20m×20m square field of grass by means of a rope of 10m long rope. Find the area of the part of the field in which the horse can't graze

Answer 1

Answer:

321.5 m^2

Step-by-step explanation:

Area of square field = 20 * 20 = 400 m^2

Area horse can graze = (90/360) * pie r^2

= (1/4) * (3.14) * (10)^2

= 0.785 * 100

= 78.5 m^2

so area of the part of the field in which the horse can't graze = 400 - 78.5

= 321.5 m^2
