Aim: How do we find the volume of pyramids and cones?

To find the volume of a cone you must use the formula (1/3) times pi times the radius squared times the height.





The volume of this figure would be 6 squared (36) time 15 (540) divided by 3 (180). You could leave this answer in terms of pi which would equal 180pi cm cubed.


To find the volume of a pyramid you have to use the formula (1/3) time base times height.







  • The volume of this pyramid would be 8 times 8 (36) times 9 (324) divided by 3 (108). The final answer would be 108 cm cubed.









    Find the volume of theses two solids:
