Question

The Coca-Cola company has developed a new soft drink. The art department has been asked to design a label fr this new drink.If the cylindrical can of Coke measures 7 inches tall and has a diameter of 3.5 inches, how much area will the label cover? Round to the nearest tenth.

Answer 1

the diameter is 3.5 inches, so the radius is d/2 = 3.5/2 = 1.75 inches


The lateral surface area is then


SA = 2pi*r*h

SA = 2pi*1.75*7

SA = 2pi*12.25

SA = 12.25*2pi

SA = 24.5pi

SA = 24.5(3.14159)

SA = 76.968955

SA = 77.0
