Question

if the radius of a circle is 14√(pi) cm then its area is​

Answer 1

• As per the data given in the question, we have to determine the required number.

           Given data:-  $14\sqrt{\pi }\ cm .$

           To find:- Area of the circle.

          Solution:-

• The diameter of a circle is the longest chord of a circle.

• Equal chords of a circle subtend equal angles at the center.

           $\text { : radius of the circle }= 14\sqrt{\pi } \\=\text { Area of the circle }=\pi \mathrm{r}^{2}\\=\frac{22}{7} (14\sqrt{\frac{22}{7} } })^{2} \\=1936cm^{2} .$

       Hence we will ger the Area of a circle is $1936cm^{2} .$

Answer 2

As per the data given in the question, we have to determine the area of the circle.

As per data,

It is  given that,

Radius of circle $14\sqrt{\pi }\ cm .$

To find:- Area of the circle.

As we know that,

Area of circle $=\Pi r^2$

So, putting the values of r in formula of finding the area.

We will get,

$radius\: of\: the \:circle }= 14\sqrt{\pi } \\=\text { Area of the circle }=\pi \mathrm{r}^{2}\\=\frac{22}{7} \times 14 {\sqrt{ \Pi}} \times 14{\sqrt{\Pi}}\\=\frac{22}{7} \times 196 \times \Pi\\=\frac{22}{7} \times 196 \times \frac{22}{7}\\1956\:cm^2$

Hence we will get the Area of a circle is $1956\:cm^{2}$.
