A clyindrical container has radius 3 cm and height 82 cm.

a) Find the surface area of the container.
b) The container is coated with 2 layers of specialty paint that costs $6.05 per jar.Each jar of paint covers 800 cm². How much does the paint cost?

So the surface area formula is \(A=2πrh+2πr^2\).

 

So you plug 3 for r and 82 for h.

 

You should get around 1602.21.

 

For part B, I'm kinda confused. When you said 2 layers, do you mean that each layer is 1 full jar of special paint? Once you respond I can try to help more.

1602.21*2=3204.42

3204.2/800=4

$6.05*4=$24.20
