A circle has a circumference of 47.1 cm and a diameter of 15 cm.

What number represents the ratio of the circumference to the diameter of this circle?

circumference/diameter = 47.1/15 = 3.14

Look familiar?

3.14 it is magic

No, it's 3.14

3.14 To find the ratio of the circumference to the diameter of a circle, you need to divide the circumference by the diameter.

The circumference of the circle is given as 47.1 cm, and the diameter is given as 15 cm.

So, the ratio is calculated as:

Ratio = Circumference / Diameter

= 47.1 cm / 15 cm

Now, divide 47.1 by 15:

= 3.14

Therefore, the ratio of the circumference to the diameter of this circle is approximately 3.14.
