Question

A horse is tied to a post by a rope. If the horse moves along a circular path, always keeping the rope tight and describes 88 meters when it traces the angle of 72° at the center, then the length of the rope is

Answer 2

Answer:

Let the post be at point P and let PA be the length of the rope in tight position. Suppose the horse moves along the arc AB so that ∠APB=72  

0

 and arc AB=88m

Let r be the length of the slope i.e PA=rmeters

Now θ=72  

0  =(72×  180π)=  5

2π  and S=88

∴θ=  radius  arc  ⇒  5

2πr  =  88 ⇒r=  2π

88×5 =70
