Question

What is the volume of the cylinder with 7cm radius and 5cm height?

Answer 1

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-
$={\displaystyle \frac{22}{7}}\times 7^2\times 5$
$=22\times 35$
$=770c{m}^2$
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.
