Question

Curved surface area of a right circular cylinder is 4.4$m^2$. If the radius of the base of the cylinder is 0.7m, find its height.

Answer 1

$\begin{array}{c}Curvedsurfacearea=4.4m^2\\ Radius=0.7m\\ 2\pi rh=4.4\\ 2\times 3.14\times 0.7\times h=4.4\\ h=\frac{4.4}{4.396}=\frac{4.4}{4.4}=1m\end{array}$
