Hint- Here we will use the formula of volume of cylinder i.e. $\pi {r^2}h$ to calculate the volume of cylinder by using the given radius of cylinder as 7cm and height of cylinder as 5cm.

Complete Step-by-Step solution:

As we are given that-
The radius of cylinder is 7cm
The height of cylinder is 5cm
Now we will apply the formula of volume of cylinder-
Volume of cylinder $ = \pi {r^2}h$
We will substitute the value of radius = 7cm and value of height = 5cm in the formula,
We get-
$ = \dfrac{{22}}{7} \times {7^2} \times 5$
$ = 22 \times 35$
$ = 770c{m^2}$
Therefore, the volume of the cylinder is $770c{m^2}$.

Note - While solving this question, we must know the formula of volume of cylinder i.e. $\pi {r^2}h$. Also we must use all the formulas of cylinder like total surface area and curved surface area of cylinder to solve all problems related to cylinder.
