Book Free DemoAll circles are similar to one another. So, the ratio of the circumference to that of diameter is a constant,
That is (pi)
Therefore (Where the approximate value of \(π\) is \(3.14\))
\(C\)\(=\) or \(C\)\(=\)
The diameter is twice the radius (\(2r\)), so the above equation can be
written as Note: \(d\ \)\(= \)\(2r\)
written as Note: \(d\ \)\(= \)\(2r\)
Therefore, the circumference of a circle, \(C = 2\)\(r\) units.
