A 8π ft


B 4π ft


C 2π ft


D.16π ft

Answer 1

Answer:

8π

Step-by-step explanation:

If we are given the diameter of this circular fence, then we can solve for the radius. Just take the diameter of 4 and divide by 2 which is 2.

The circumference of a circle is 2πr²

Just plug in the variables and you get 2π(2)² which is 8π

Hope this helps! :)
