You need to make a soda can with a volume of 29 cubic inches.

Find the surface area. calculate the following:
a) How much material is needed if the can's radius is 1 inch?

2 answers

let the height be h
volume = πr^2h
π(1^2)h = 29
h = π/29

the surface area are
top + bottom + rectangle forming the outside of the cylinder
= 2πr^2 + 2πrh
= 2P(1) + 2π(1)(π/29)
= .....
= 64.28319 in^2

thank you!
