Answer 1

the answer is B

Explanation:

Answer 2

B. 43.3 cm

Explanation:

The formula for the circumference of a circle is
`2 \pi r` if you want it in terms of the radius but you can also say the circumference is
`d \pi` if you want it in terms of the diameter since you know the radius is twice the diameter.

So we are actually given the diameter which is 13.8 cm.

So the Circumference is just pi times that.

So I'm going to put pi times 13.8 in my calculator and select the closest answer.

13.8*pi=43.35 cm.
