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?

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

the word superfluous means unnecessary

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
