Question

If the lateral surface of a cylinder is 94.2 cm^2 and its height is 5 cm , find its radius.​

Answer 1

Answer:  Given :

               $\pi$= 3.14 , h = 5cm

Lateral surface of cylinder = 2πrh

                $94.2cm^{2} = 2*3.14 *r*5\\94.2=3.14*10*r\\94.2 = 31.4*r\\94.2/31.4=r\\r=3 cm$
