Question

In a circle, what is the ratio of the circumference to its diameter?

Answer 1

Answer:

D. pi

Step-by-step explanation:

Circumference of a circle = $\pi d$

Diameter = d

Therefore, ratio of circumference of a circle to its diameter would be:

$\pi d : d$

$= \frac{\pi d}{d} = \pi$ => (d cancels d)

Therefore, the ratio of the circumference of a circle to its diameter is $\pi$
