Question

A goat is tethered to a circular silo in the middle of a grassy field by a rope equal in length to one-half of the circumference of the silo. What is the area of grass over which the goat can graze?

Answer 1

Answer:

π²x

Step-by-step explanation:

Suppose radius of the silo = x

circumference of the silo = 2πr

                                          = 2πx

Given that,

length of rope is equal to one-half of the circumference of the silo

l = 1/2(2πx) = πx

Formula to calculate area of grass over which the goat can graze

πl²

ππx

π²x
