Question

The radius of a circle is 6. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
A) C/6 = π
B) C/12= π
C) C = 6πr
D) C = r12π

Answer 1

Answer:

The ratio of circumference of circle and diameter of circle is π

B is correct

Step-by-step explanation:

The radius of a circle is 6.

We need to find the ratio of circumference of circle and diameter

Circumference of circle = 2πr

                                   C = 12π

Diameter of circle = 2r

                        D = 12

Substitute 12 as D

Now we find the ratio of circumference and diameter    

$\dfrac{C}{12}=\dfrac{12\pi}{12}$

$\dfrac{C}{12}=\pi$

Hence, The ratio of circumference of circle and diameter of circle is π

         

Answer 2

I believe C/12=pi which means the answer would be B.
