Question

Farmer Jones wants to make a circular corral for his horses. If the diameter is to be 500 m,

how many meters of fencing is needed? Round to the nearest whole number? Use 3.14 for .

Answer 1

1571m

Explanation:

Step one:

given data

the diameter of the farm= 500m

the radius will be d/2

= 500/2

r=250m

Step two:

Required

The perimeter fence for the farm

this is also the same as the circumference of the farm

C=2πr

C=2*3.142*250

C=1571m

Hence the needed length of fence is 1571m
