Q : 4    If the lateral surface of a cylinder is \small 94.2\hspace{1mm}cm^2 and its height is 5 cm, then find

            (ii) it's volume. (Use \small \pi =3.14)
 

Answers (1)

Given,

The lateral surface area of the cylinder = \small 94.2\hspace{1mm}cm^2

Height of the cylinder = h = 5\ cm

The radius of the base is 3\ cm

(ii) We know,

The volume of a cylinder = \pi r^2 h

\\ = 3.14\times3^2\times5 \\ = 3.14 \times 9 \times 5= 3.14 \times 45 \\ = 141.3\ cm^3

Therefore, volume of the cylinder is 141.3\ cm^3
