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

Question

Responses

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

A=πr2
upper A equals pi r squared

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

C/d=π

Answer 1

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

$C/d=\pi$

This means that the circumference is π times the diameter. Therefore, the correct response is:

C/d=π
