Which formula correctly describes the proportional relationship between the circumference of a circle and the diameter?(1 point)

Question

Responses

A=πr^2
upper A equals pi r squared

C=π/d
upper C equals Start Fraction pi over d End Fraction

π=d/C
pi equals Start Fraction d over upper C

C/d=π
Start Fraction upper C over d End Fraction equals pi

Answer 1

The correct formula that describes the proportional relationship between the circumference of a circle (C) and the diameter (d) is:

\[ C/d = π \]

This indicates that the circumference divided by the diameter is equal to π, which is a constant value.

So the correct response is: C/d = π
