Answer:

C. 144.44 m

Step-by-step explanation:

You have two ways to calculate the circumference [C = π*d] [C = 2*π*r]. Each depends on the given you have. Both ways work and give the same answer.

In the given you have π and a radius r so we will use the second equation I mentioned.

So C = 2πr (Now let's substitute)

C = 2x3.14x23

=144.44 m

and there you have it. :)
