Question

Given a circle with a radius of 3, which equation expresses π as the ratio of the circumference of a circle to its diameter?

Answer 1

C /6

= π

Explanation:

Remember, d = 2r.

C = 2πr

C = 2(3)π

C = 6π

C

6

= π

Answer 2

The diameter is 6 because double the radius is 6. The cirucmference is 3.14*6. You get 18.84. The ratio is 18.84 to 6. Hope this helped.
