Question from Amirah: What is the volume of a polystyrene cup with a height of 8cm, diameter of 5cm at the top and 4cm at the bottom when it is filled with water? |
Hi,
The shape you describe is called a truncated cone. I have taken am image of a coffee cp and extended the sides to make a cone.
The volume of the cup is the volume of the entire cone minus the volume of the yelow extension.
