Question

The net for a cylindrical container that holds a stack of DVDs is shown below. What is the total area of the net?

Answer 1

`301.714 cm^2`

Explanation:

Radius of cylinder = 6 cm

Height of cylinder = 8 cm

We are supposed to find that total surface Area of cylinder

Since the net is not closed so we will used curved surface area

Total surface area of net =
`2\pi rh`

=
`2 * (22)/(7) * 6 * 8`

=
`301.714 cm^2`

Hence the total area of the net is
`301.714 cm^2`

Answer 2

The surface area of each of the circles is 36π, and their circumference is 12π. The area of the rectangle is the circumference of the circle times 8, or 12π*8=96π. 96π+2(36π)=96π+72π=168π square units. Hope this helps!
