Question

the area of circumference of a circle is 17.6cm .find the area of the circle

Answer 1

Circumference : 2*pie*r
2 * 22/7* r= 17.6
r = 17.6 * 1/2 * 7/22
= 2.8 cm

area= 22/7 * 2.8* 2.8
33.44 cm^2

Answer 2

circumference of circle=
$2\pi \times r$
:.17.6=2×22/7×r

17.6×7/44=r

2.8 cm=r

now ,

area of circle =
$\pi {r}^{2}$
:.22/7×2.8×2.8

=8.8×2.8

=33.44cm^2..

hope it helps you
