Why circumference of circle is 2×pai×radius ? |
| Answer» π\xa0is defined to be the ratio of the circumference of a circle over its diameter (or 2 times its radius).This ratio is a constant since all circles are geometrically similar and linear proportions between any similar geometric figures are constant.If you were looking for how the value of the ratio\xa0π\xa0is calculated or how we know that the same ratio applies to the area of a circle, then those are different questions. (Ask if either of these are what you were looking for). | |
