Question

Ali is constructing a cylindrical water tank made out of polyethylene. He wants to find the volume of the water tank and the mass of the water tank given the standard density and volume of the tank. Explain with thorough steps of how Ali can find these calculations if the water tank is hollow and not solid. Given:Height of water tank = 8ftWidth of water tank = 5ftDensity of polyethylene = 0.900 g/cm3

Answer 1

Answer

Explanation

Given

• Height of water tank = 8ft

• Width of water tank = 5ft

• Density of polyethylene = 0.900 g/cm³

Procedure

The volume of a hollow cylinder V is given by:

$V=\pi\cdot h\cdot\frac{(D^2-d^2)}{4}$

where D is the bigger diameter, d is the smaller diameter, and h is the height.

We are given the height and the width would be the diameter of
