Answer:
Ratio of circumference of the circle to the circle's diameter = π : 1
Step-by-step 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
