A cone with a slant height of 10 cm. Find: The relationship between the volume of the cone and the angle 0. 10 I. Making Conjectures 1a) Sketch the cone with a very small angle , keeping in mind that the slant height is constant. Describe the effect on the radius and height of the cone. b) Sketch the cone with a very large angle , keeping in mind that the slant height is constant. Describe the effect on the radius and height of the cone. c) Make a conjecture regarding which type of angle would create a larger volume. Justify your answer. The formula for the volume of a cone is V = = r h. zarh. 3
