Volume of cones
Cones
The volume of a cone works on area of the base multiplied by height and some factor.
Area of base = πr2
Volume of cone = 13×volume of a cylinder
Volume of cone = 13×Area of base× height
Volume of cone = 13×πr2× height
3 cones fill 1 cylinder (with the same size base and height).
NOTE:
Areas shaded blue are all equal.
