C) radius to diameter
D) circumference to diameter

Answer 1

D. Circumfrence to diameter is the answer  

Answer 2

Answer: D) circumference to diameter

Explanation:

We know that circumference of a circle is given by :-

`C=\pi d`, where d is the diameter of the circle.

Therefore, the ratio of circumference to diameter of a circle will be

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

Hence,
`\pi \text{ is the ratio of circumference to diameter.}`
