The radius of a circle is 10. using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?

π = C / d

Step-by-step explanation:

The circumference of a circle is given by the general formula;

C = 2 * π * r or C = π d  (r = radius, d = diameter)

We can easily modify the second formula to isolate π in order to express the circumference in relation to the diameter:

π = C / d

To obtain π, you need to divide the circumference by the diameter.

We're used to think about the circumference in terms of radius... but since we deal with 2 * r * π and that 2 * r = d...  it's also convenient to use the diameter.
