Answer 2

$\mathrm{Let\:area\:of\: cylinder\:=R cm}$

$\mathrm{Height\:=3\:cm}$

$\mathrm{Lateral\: surface\:area\:=18.48cm²}$

$2\pi rh = 18.48$

$\: \: \: \: \: ⇒2 \times 3.14 \times r \times 3 = 18.48$

$\: \: \: \: \: ⇒12.84 \times r = 18.48$

$\: \: \: \: \: ⇒r = \frac{18.48}{12.84}$

$\: \: \: \: \: ⇒r= 1.925844265cm$
