Given:

त्रिज्या 14 सेंटीमीटर है |

To find:

उस वृत्त का क्षेत्रफल ज्ञात कीजिए|

Solution:

The radius of the circle, r = 14 cm

We know the formula of the area of a circle is as follows:

$\boxed{\bold{Area\:of\:a\:circle = \pi r^2}}$

Now, by using the above formula, we get

The area of the given circle is,

= $\pi\times (14)^2$

on substituting as given $\pi = \frac{22}{7}$

= $\frac{22}{7} \times (14)^2$

= $\frac{22}{7} \times 196$

= $22 \times 28$

= $\bold{616\:cm^2}$

Thus, the area of the circle is → 616 cm².
