Question

Curved surface area of a right circular cylinder is $4.4m^2$. If the radius of the base of the cylinder is 0.7 m, find its height. $[Assume\pi =\frac{22}{7}]$

Answer 1

Let the height of the circular cylinder be h.
Radius (r) of the base of the cylinder = 0.7 m
CSA of cylinder $=4.4m^2$
$\Rightarrow (2\times \frac{22}{7}\times 0.7\times h)=4.4m^2$
So, h = 1 m
Therefore, height of the cylinder is 1 m.
