Soup can problem

Question

A cylindrical soup can is 5.5 cm in diameter and 11.2 cm tall.

What formula must you use to find the area of the label that covers the side of the can?

Answer 1

Area = diameter time pi times height

A=dpi(h)

= 5.5pi(11.2)

= about 5.5(3.14)(11.2)

= 193.424 cm^2

the area = the circumference times height.

circumference = diameter times pi
