Help me with this question

I am assuming that you will need to find the circumference of the circle.

Here is the original formula for finding the circumference using diameter:

C= πd

Because we should use 3.14 for pi and we are given the diameter our problem will now look like this:

C=3.14(15)

By multiplying these two together, our answer will be:

B. 47.1

Hope this helps!
