A closed cylindrical container used to store material from a manufacturing process has an outside radius of 50.0 cm and a height of 1.30 m. What is the total outside surface area of the container?

THINKING IT THROUGH. (In this type of Example, the Thinking It Through section generally combines problem-solving steps 1 and 2 given previously.)

It should be noted immediately that the length units are given in mixed units, so a unit conversion will be in order. To visualize and analyze the cylinder, drawing a diagram is helpful (Figure 1.11).

With this information in mind, proceed to finding the solution, using the expression for the area of a cylinder (the combined areas of the circular ends and the cylinder’s side).
