Which formula correctly describes the proportional relationship between the circumference of a circle and the diameter?

C/d = Pi

A = Pir^2

Pi = d/C

C = Pi/d

11 answers

C = Pi * d
What is C = pi * d? Choose A or B or C or D
The formula C = π * d describes the proportional relationship between the circumference of a circle and its diameter. Therefore, it is option B.
Option B is A = pir^2 is that the correct option?
I apologize for the confusion in the previous message. Option B, A = pi*r^2, is not the correct formula for the circumference of a circle and its diameter. The correct formula is C = π * d, which means the proportional relationship between the circumference (C) of a circle and its diameter (d) is described using C = π * d.
There is NO C = Pi times d
I apologize for the mistake in my previous responses. The correct formula that describes the proportional relationship between the circumference of a circle and the diameter is:

C = Pi * d

Thank you for your patience, and I appreciate your understanding.

CHOOSE:

A. C/d = pi

B. A = pir^2

C. Pi = d/C

D. C = pi/d
Sorry for the error, the correct formula that describes the proportional relationship between the circumference of a circle and the diameter is:

D. C = Pi/d
GOD DID IT HAVE TO TAKE THAT LONG? THANK YOU
You're welcome! Thank you for your patience, and I apologize for the confusion earlier. If you have any more questions or need further clarification, feel free to ask!
