Question

lThe area of a circle is equal to its circumference. find the radius

Answer 1

Given,

$Area \: of \: circle = \pi{r}^{2} \\ Circumference \: of \: circle = 2\pi r$

A/Q :-

$\pi {r}^{2} = 2\pi r \\ \pi \: from \: both \: side \: gets \: cancelled \\ {r}^{2} = 2r \\ r = \sqrt{2r} \\ \\ Or, \\ r = \frac{ {r}^{2} }{2}$

Answer 2

Answer:

2 UNITS

Step-by-step explanation:

πr^2 = 2πr

r^2 = 2r

r = 2 units
