T.i.P.S.

Students should be familiar with threedimensional figures including cylinders, cones, and spheres and identify the attributes of the figure including Base, height, and/or radius from previous grade levels. Students should have an understanding of why the formula works and how the formula relates to the measure (volume) and the figure. Students must be able to solve problems and determine the solutions in problems related to finding the volume of cylinders, cones, and spheres.
Example

An ice cream cone can hold about 33.5 cm3 of ice cream. If the radius of the cone is 2 cm, what is the approximate height of the cone? Justify your thinking.
