Calculating the Volume of a Cylinder

The video tutorial explains the concept of volume as the space occupied by an object. It uses an activity involving biscuits to demonstrate how to calculate the volume of a cylinder. The tutorial describes the cylindrical shape formed by stacking biscuits and derives the formula for the volume of a cylinder as the area of the base circle multiplied by the height, expressed as Pi times the radius squared times the height.

What does the volume of an object represent?

• The weight of the object

• The length of the object

• The amount of space the object occupies

• The surface area of the object

What shape is formed by piling up the biscuits?

• Square

• Rectangle

• Cylinder

• Circle

What is the formula to calculate the area of each biscuit if they are circular?

• 2 * Pi * r

• 2 * r

• Pi * r * r

• Pi * r

How do you calculate the volume of the cylinder formed by the biscuits?

• Pi * r * h

• Pi * r * r * h

• Pi + r + h

• 2 * Pi * r * h

What is the significance of 'h' in the formula for calculating the volume of a cylinder?

• The height of the cylinder

• The radius of the base circle

• The volume of the cylinder

• The diameter of the base circle
