Answer:

Ratio of circumference of the circle to the circle's diameter = π : 1

Explanation:

Radius of the circle is given to be 6 units

So, Diameter of the circle will be 2 × radius

So, Diameter of the circle will be 2 × 6

⇒ Diameter of the circle = 12 units

Circumference of the circle = 2π × radius

⇒ Circumference of the circle = 2π × 6

⇒ Circumference of the circle = 12π units.

Now, ratio of circumference of the circle to the circle's diameter = 12π : 12

⇒ Ratio in the simplest form = π : 1
