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.

$C = 2\pi r$ ignore the 2, it causes confusion.

$d = 2r$

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

$C = \pi d$

$\pi d = \pi * 32$

$\pi * 32 = 100.53096491487338363080458826494$

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