The circumference of a circle is 2*pi*radius.
Therefore,
2*3*pi = 6*pi
so the third choice you have there

C = 2*pi*r.
Therefore, C = 2*pi*3 = 6(pi) inches

to find the circumference use the equation 2(pi)R with R of course being your radius. so 2*(3.14159)*3

circumference = 2*pi*r
Just plug in radius and solve.
