Question

Find the area of a circle whose radius is $14Cm$.

Answer 1

Compute the area:

Area of a circle with radius $r$ is given as $\mathrm{\pi }\times {\mathrm{r}}^2$.

Given that, radius of circle is $14Cm$.

By the formula,

Area $=\mathrm{\pi }\times {14}^2$

$\Rightarrow$Area $=\frac{22}{7}\times 14\times 14\left[\because ,\mathrm{\pi }\approx \frac{22}{7}\right]$

$\Rightarrow$Area $=22\times 2\times 14$

$\Rightarrow$Area $=616{Cm}^2$

Hence, area of the circle with radius $14Cm$ is $616{Cm}^2$.
