Question

if the perimeter and the area of a circle are numerically equal,tgen the radius of the circle is​

Answer 1

$\large{\mathcal{\blue{Answer}}}$

according to the quesion:

$\pi \: r {}^{2} = 2\pi \: r \\ \frac{\pi \: r {}^{2} }{\pi \: r} = 2$

$\huge{\mathcal{\purple{\boxed{r=2}}}}$

Answer 2

ANSWER....

$area \: of \: circle = \pi {r}^{2} \\ \\ perimeter \: of \: circle = 2\pi \: r \\ \\ where \: r \: is \: the \: radii \: of \: the \: circle \\ \\ acc \: to \: your \: question \\ \\ area \: of \: circle = perimeter \: of \: circle \\ \\ \pi {r}^{2} = 2\pi \: r \\ \\ r = 2 \: units$
