Question

the circumference of a circle is 176 cm. find its area?

Answer 1

2 pie r = 176
2×22/7×r 176
r= 176×7 /44
r=28 cm
use,
area of circle= pie r^2
=,22/7×28×28
2464 cm^2

Answer 2

$\huge \boxed{\texttt {\fcolorbox {red} {aqua} {SOLUTION :-}}}$

Given,
$2 \pi \: r$ = 176

=> 2 ×22/7× r = 176

=> 44r/7 = 176

=> 44r = 176 × 7

=> r = 176 × 7 /44

=> r = 28

The radius of the circle, r = 28 cm

So, the area will be
$\pi \: r {}^{2}$ = 22/7 × 28 × 28

= 22 × 4 × 28

= 2464 cm^2
