Question

How many meters of chicken wire do you need with a diameter of 2.9 meters

 

Answer 1

1) The question is asking us how many meters we need to make a circular pen, in other words the circumference. 

 

2) To determine what the circumference is, we follow the formula Circumference = (PI) x Diameter 
Note: PI = π = 3.14...

 

3) The circumference of the circular pen would be 2.9 x (PI), which is equal to about 9.106 (in 9) meters.

 

4) Therefore, we need about 9.106 (or 9) meters to build a circular pen with a diameter of 2.9 meters. 

 

Answer: 9.106 meters (or 9 meters)
