Surface Area of Right Cylinders, Cones, and Spheres
Objective
Apply formulas for surface area of right cylinders, cones, and spheres.
About Geometry Worksheet Assignment 10.19:
Assignment 10.19 is an introduction to surface areas of right cylinders, cones, and spheres.
Prerequisite Skills: Calculate the area of a circle (Assignment 10.16). Identify the radius and diameter of a circle (Assignment 10.1).
2
Theorems: The formula for the surface area of a right cylinder is: S = 2 r + 2 r h (h is the height of the cylinder; r is the radius of the base)
2
The formula for the surface area of a right cone is: S = r + r l (l is the slant height of the cone; r is the radius of the base)
2
The formula for the surface area of a sphere is: S = 4 r (r is the radius of the sphere)
