Question

450 cubic centimetres of wood is used to make a solid cylindrical ornament. The radius of the bas of the ornament is 5 centimetres. What is the height of the cylindrical ornament?

Answer 1

`5.73\text{ }cm`

Step-by-step explanation

We want to find the height of the cylindrical ornament.

To do this, we have to apply the formula for the volume of a cylinder:

`V=\pi r^2h`

where r = radius

h = height

To find the height of the ornament, substitute the given values into the equation and solve for h:

`\begin{gathered} 450=\pi *5^2*h \\ \\ h=(450)/(\pi *5^2) \\ \\ h=5.73\text{ }cm \end{gathered}`

That is the answer.
