Question

FIND THE AREA OF THE CIRCLE (TAKE Π22\7 ) RADIUS=21 CM
$\pi$
​

Answer 1

Given, radius r=21cm and π=

7

22

Then,

Area of the circle = πr

2

sq units

=

7

22

×21×21

=22×3×21

=1386cm2

Answer 2

Step-by-step explanation:

We know, Formula of the area of a circle is $\pi r^{2}$.

Let area be x

By data,

x = $\frac{22}{7}$*21*21

x = 22*3*21 (We canceled 7 with 21, which is 3 times 7)

x = 1386 $cm^{2}$

∴ The required area for the circle is 1386 $cm^{2}$

Hope it helped.
