Which equation shows how the relationship between the circumference and the diameter of a circle is equivalent to π?

a) π = dc
b) π = d c
c) π = c d
d) π = 1 dc

The answer to your question is: I think is letter C

Step-by-step explanation:

Formula of circumference

                                           C = 2πr

where

C = circumference

r = radius

d = diameter

and

r = d/2

then

                                        C = 2 π d/2

                                        C = πd

                                        π = C/d     It is a division
