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

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

Answer 2

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

B is correct

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

`(C)/(12)=(12\pi)/(12)`

`(C)/(12)=\pi`

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