Question

A juice can is 16 cm tall and has a diameter of 9 cm. The ends of the can are tin and the body is cardboard.

a) What is the volume of the can?

b) What area of tin is used?

c) What area of cardboard is used?

d) What is the total surface area?

Answer 1

I'll setup the problem and you can do the calculations

Explanation:

a.

`V = \pi( {D}^(2) / 4)H`

V = volume; D = diameter; H = height of can

b.

Area of the Tin is the total area of the 2 Tin circles

one circle's area A is

`A = \pi {D}^(2) / 4`

A = area; D = diameter

calculate A

Then multiply by 2

c.

The area of the cardboard is the circumstance of the circle

times the height

`SA = \pi DH`

d.

add answers from b and c
