Question

Find the circumference of circle whose radius is $14cm$.

Answer 1

Given radius $r=14cm$
Circumference of the circle with radius $r$ is =$2\pi r$

$=2\pi \left(14\right)$ [Since $r=14$]
$=\frac{2\times 14\times 22}{7}$ [Since$\pi =\frac{22}{7}$]

$=4\times 22$

$=88cm$
Hence, the circumference of the given circle is $88cm$.
