    Students will begin this activity by investigating the volume of a cylinder that is not necessarily right. The radius of the base and the height of the cylinder are fixed, but the angle of the cylinder changes when students move point A. Students will discover that the volume does not depend on the angle of the cylinder if the cross sectional area remains fixed.
