Answer:If the diameter is 13 you should try each answer until you find pi.

To find pi you have to divide the circumference by the radius.

You don't need to find the circumference in this question but you can.

The circumference is 40.82

Then you have to divide

40.82÷13

that equals 3.14

and because that is pi, C is your answer
