Question

A cow farmer has decided to surround her circular farm with a wooden fence to protect the cows from wolves. If the radius of the circular farm is 32 yards, what will be the total length of the fence?

Answer 1

201.14 yards

Explanation:

The fence covers the perimeter of the farm.

Since the farm is circular, the perimeter a circle would be used to determine the total length of the fence

perimeter = 2nr

n = 22/7

r = radius = 32

2 x (22/7) x 32 = 201.14 yards
