### Solve

Set up a system of equations for circumference and diameter. Circumference will be the value of pi times diameter, and diameter will be radius, which we do not find for this case.

ignore the 2, it causes confusion.

Now that you have your system partially set up, put these values of Circumference(C ) and diameter(d ) into a full equation.

Remember when finding circumference by diameter, multiply pi by the value of the diameter for your answer.

### What have we learned?

We learned how to find circumference by using diameter and pi in a system of equations.
