2 Cylinders and ConesA cylinder is like a prism except that its bases are circles instead of polygons.In a right cylinder, the segment joining the center of the circular bases is an altitude.The length of the altitude is the height.A radius of a base is the radius of a cylinder
3 Cylinders and Cones Theorem 12 – 5 The lateral area of a cylinder equals the circumference of a base times the height of the cylinderTheorem 12 – 6The volume of a cylinder equals the area of a base times the height og the cylinder.
4 Cylinders and ConesA cone is like a pyramid except that its base is a circle instead of a polygon.Just like a regular pyramid has a slant height a right cone also has a slant height.
5 Cylinders and Cones Theorem 12 – 7 The lateral area of a cone equals half the circumference of the base times the slant height.Theorem 12 – 8The volume of a cone equals the area of a base times the height of the cone
6 Cylinders and ConesA cylinder has a radius 5cm and height 4 cm. Find the lateral area, the total area, and the volume of a cylinder.45
7 Cylinders and ConesFind the lateral area, total area, and volume of a cone that has a radius of 3 and a height of 663
