Calculating Surface Area of Cylinders and Prisms

What is the first step in finding the lateral surface area of a cylinder?

• Multiply the radius by the height

• Shade the bases and identify the height

• Divide the diameter by 2 to find the radius

• Add the areas of the bases to the lateral surface area

How do you find the total surface area of a cylinder?

• 2(r + h) pi

• pi r squared h

• 2 pi r h + 2 pi r squared

• 2 pi r squared

What formula is used to find the lateral surface area of a rectangular prism?

• Length plus width plus height

• 2 times the area of the base

• Length times width times height

• Perimeter of the base times height
