Question

Find the area of the quadrant of a circle whose circumference is 44.

Answer 1

Circumference of circle=44
2^r=44
44r/7=44....
so,
r=7cm....
Area of quadrant=1/4^r2..
.............................=1/4×22/7×7×7
...............................=154/4=32.5
here,is your ans....

Answer 2

let the radius of circle =r
$circumference \: of \: circle = 2\pi \: r \\ according \: to \: question \: circumference \: = 44 \\ therefore \\ 2\pi \: r = 44 \\ r = \ \frac{44}{2\pi }$
r =7
$area \: of \: circle = \pi {r}^{2}$
=22/7×7^2
=22×7
= 154
