Question

The circumference of the circle is 396 m. Find the area of the circle.

Answer 1

$\huge{Answer \ :-}$

Circumference of circle = 396 m

2 π r = 396

2 × $\dfrac{22}{7}$ × r = 396

r = 396 × $\dfrac{7}{22×2}$

r = 63 m

Area of Circle = π ${r}^{2}$

= $\dfrac{22}{7}$ × ${63}^{2}$

= ${12474\ m}^{2}$

Thanks !!

Answer 2

HEY MATE!!!


CIRCUMFERENCE OF CIRCLE = 396 m

$2\pi \times r = 396$
$2 \times \frac{22}{7 } \times r = 396$
$\frac{44}{7} \times r = 396$
$r = 396 \times \frac{7}{44}$
$r = 63m$
AREA OF CIRCLE =
$= \pi \times {r}^{2}$
$= \frac{22}{7} \times {63}^{2}$
$= \frac{22}{7} \times 63 \times 63$
$= 12474 {m}^{2}$
