Question

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

Answer 1

Given: Curved surface area of a right circular cylinder $=4.4m^2$.

Radius, $\left(r\right)=0.7m$

Let the height of the given cylinder be $h.$

We know that the Curved surface area of the cylinder is given by $2\pi rh$

$2\pi rh=4.4m^2$

$\Rightarrow 2\times \frac{22}{7}\times 0.7\times h=4.4$

$\Rightarrow h=\frac{4.4\times 7}{2\times 22\times 0.7}=1m$

Hence, the height of the given cylinder will be $1m$
