Question

consider a circle with diameter of 12cm what is the circumference of the circle what is the ratio of the circumference to the diameter​

Answer 1

Circumference of the circle:
`12\pi`

Ratio of the circumference to the diameter:
`\pi`

Explanation:

First, we are finding the circumference of the circle using the circumference formula:

`C=\pi d`

were

`C` is the circumference of the circle

`d` is the diameter of the circle

We know from the problem that the diameter of our circle is 12cm, so
`d=12`.

Replacing values:

`C=\pi d`

`C=\pi (12)`

`C=12\pi`

Now, to find the ratio of the circumference to the diameter, we just need to divide the circumference of our circle by the diameter:

ratio =
`(12\pi )/(12) =(\pi )/(1) =\pi`

Answer 2

Circumference = πd = 37.68

Ratio = 3.14 or pi

Explanation:

Points to remember

Circumference of circle = πd or 2πr

Where d - diameter and r is the radius

It is given that, a circle with diameter 12

To find the circumference

Circumference = πd = 12π or

To find the ratio

circumference = 12 * 3.14 = 37.68 cm

Ratio = circumference/diameter​

= 12π/12 = π or 3.14
