Answer:
10
Step-by-step explanation:
2^2 x 5^2 = 100
root the 100 = 10
The length of the rope with which the horse is tied becomes the radius of the circular area.
Length of rope = 5 m
Area within which the horse can graze
= pi * r^2 = 3.14 * 5 = 15.7 m^2
Area of the grassland at the Centre of which the horse is tied = 3.14 * 25
= 78.5 m^2
Area in which the horse cannot graze
= Area of grassland - Area in which the horse can graze
= 78.5 - 15.7
= 61.8 m^2
Answer:
Part a) 
Part b) 
Step-by-step explanation:
step 1
we know that
The diameter of the circle divide the circle into two equal parts
so
PM=MQ
Applying the <u>Intersecting Chord Theorem</u> (When two chords intersect each other inside a circle, the products of their segments are equal)
we have
substitute
step 2
Find the value of PQ
we know that
so
we have
substitute
