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

Given: Radius of the circle is $14\ cm$.

To do: To find the circumference and area of the circle.

Solution:

Radius of the circle $r=14\ cm$

$\therefore$ Circumference $=2\pi r$

$=2\times\frac{22}{7}\times14$

$=88\ cm$

Area of the circle $A=\pi r^2$

$=\frac{22}{7}\times 14\times14$

$=616\ cm^2$

Thus, the circumference and area of the circle are $88\ cm$ and $616\ cm^2$ respectively.
