CAN U help me to solve add math project?

Question

the top and bottom pieces of the tin of height h cm are cut from square-shaped aluminium sheet.
determine the value for r,h and hence the ratio h/r so that the total area of the aluminium sheets used for making the tin is aluminium <>

Answer 1

The total area or the can is give by:
Area of curved surface = 2π r h
Area of top of can = π r²
Area of bottom of can = π r²
-----------------------------------------
Total area (A) of can = 2π r h + 2 π r²
A = 2π r h + 2 π r²
A - 2 π r² = 2π r h
(A - 2 π r²) / 2π r = h
h = (A / 2π r) - r

It's the best I can do for you based on the information given.

Answer 2

"The total area of the aluminium sheets used for making the tin is aluminium"????????

Refer to what diagram?

If you expect other people to do your homework for you, the least you can do is give them a sensible question.

Answer 3

The aluminum sheets are square shape

The area formula for a square is

A = s²

Example

The sides length and width measure 5 inches each

A = 5²

A = 25

The answer is A = 25

The area is 25 inches
