Question

find the area of circle circumscrimbing a sauare of side 6 cm

Answer 1

area of square = 4a square =4×4 =16 . ans. hope that this will help you out.!!

Answer 2

diary, eternal must be the diagonal of the square..
So diameter is
$\sqrt{2} a$
$=6 \sqrt{2}$
therefore radius is 1/2 of diameter
$r = 3 \sqrt{2}$
area of circle
$= \pi {r}^{2}$

$= \frac{22}{7} \times 3 \sqrt{2 } \times 3 \sqrt{2}$
$\frac{396}{7}$
$= 56.57 {cm}^{2} \: {approx.}$
