The radius of a cylinder is $7\ cm$. and its height is $10\ cm$. Find the curved surface area and volume of the cylinder, $( use\ \pi=\frac{22}{7})$.
Given: The radius of a cylinder is $7\ cm$ and its height is $10\ cm$.
To do: To find the curved surface area and volume of the cylinder.
Solution:
As given
Radius of cylinder $( r)=7\ cm$
Height $( h)=10\ cm$
Curved Surface Area of cylinder $=2\pi rh$
$=440\ cm^2$
Volume $=\pi r^2h$
$=\frac{22}{7}\times7\times7\times10$
$=1540\ cm^3$
Thus, the surface area of the cylinder is $440\ cm^2$ and the volume of the cylinder is $1540\ cm^3$.
