A horse is tried to a pole fixed at one corner of a 30m×30m square field of grass by a 10m long rope. Find the area of that part of the field in which the horse can graze.
Answers
Answer:
78.5 M
Step-by-step explanation:
Side of a square =30 m
Length of the rope = Radius of the sector
∴ Radius of the sector r=10 m
Measure of arc θ=90
