Campbell Soup is creating a new soup label. If a can has a height of 6 in and a diameter of 4 in, how much material does Campbell need for each soup label? Use 3.14 for π. Which formula can be used to find the surface area of the label?

• SA = 2πrh + 2r²

•  SA = 2πrh

• SA = Ph + 2B

• V = Bh

What is the surface area formula for a cylinder? 

• S = 2πrh +2πr²
• S = Ph + 2B
• S = πrl + πr²
• S = ½Pl + B

If you are asked to find the measurement of a lable off of a soup can, what are you being asked to find?

Find the surface area of the cylinder. (HINT: Make sure you use the RADIUS!)

• 100.53 square inches
• 351.86 square inches
• 251.33 square inches
• 50.27 square inches

Find the surface area of the cylinder.

• 471.24 square centimeters
• 157.08 square centimeters
• 314.16 square centimeters
• 296.72 square centimeters

Find the lateral surface area of the cylinder.

• 471.24 square centimeters
• 157.08 square centimeters
• 314.16 square centimeters
