Philip pours wax in the candles which is in cylindrical shape.

The amount of wax is used is equal to the volume of the cylinder.

The general expression for the Volume of the Cylinder is :

$\text{ Volume of Cylinder = }\Pi(radius)^2Height$

In the given figure of cylinder, Radius = 3 in, Height = 5.5 in

Substitute the value and solve for Volume :

$\begin{gathered} \text{ Volume of Cylinder = }\Pi(radius)^2Height \\ \text{ Volume of Cylinder = 3.14}*3*3*5.5 \\ \text{ Volume of Cylinder = }155.51in^3 \end{gathered}$

As, the amount of the wax used is equal to the volume of cylinder

Amount of wax used is 155.51 cubic inches

Answer : 155.51 cubic inches
