Help with number 5 pleaseeee

Answer:
(A) 125.6 m
Step-by-step explanation:
They are asking the circumference of a circle with a radius of 20. The formula for the circumference of a circle is:
[tex]C=2\pi r[/tex], where C is the circumference and r is the radius.
Plug in [tex]r=20[/tex] to get:
[tex]C=40\pi[/tex] which is approximately 125.6.
Hope this helps :)
