Course 3 8-6 Volume of Cones 1313 V = 9 6 V = 18 56.5 m 3 V = Bh 1313 B = (3 2 ) = 9 m 2 Use 3.14 for . Word Problem 6 m 3 m An ice cream package is cone shaped. It has a radius of 3 cm and a height of 6 cm. Find the volume of the cone? Use 3.14 for .

11
Course 3 8-6 Volume of Cones Additional Example 2: Exploring the Effects of Changing Dimensions A cone has a radius of 3 ft. and a height of 4 ft. Explain whether tripling the height would have the same effect on the volume of the cone as tripling the radius. When the height of the cone is tripled, the volume is tripled. When the radius is tripled, the volume becomes 9 times the original volume.

12
Lesson Practice Find the volume of each figure to the nearest tenth. Use 3.14 for . 78.5 in 3 Insert Lesson Title Here Course 3 8-6 Volume of Cones 1. the cone
