Volume of a Cone
What does the volume of a pyramid have to do with the volume of a cone? Young mathematicians derive the volume formula for cones by considering how the cone's cross-sectional areas compare to that of a rectangular pyramid. Solutions will...
Lesson Planet
Volume of a Pyramid
It takes three to add up to the whole. Pupils use drawn-in line segments in a triangular prism to show that it can be divided into three pyramids. Learners use what they know about prisms to show the bases of the three pyramids and their...
Lesson Planet
Volume of a Cylinder
It's all about having equal cross-sectional areas and equal heights. Using a diagram of a prism and a cylinder, pupils explain the formula of the volume of a cylinder. Individuals use facts about the relationship between the prism and...
