Answer:
It costs $0.216 to make smaller can and $0.324 to make larger can
Step-by-step explanation:
Given:
The ratio of the surface areas = 4:9
Area of smaller cans = 36 sq in
Cost = $0.006 per square inch
To Find:
how much does it cost to make each can = ?
Solution:
Lets the area of the larger can be x
the ratio is 4 : 9
then 4x = 9.(36)
4x = 216

x = 54
The area of the larger can is 54 sq in
Now the cost of making the smaller can =
= $0.216
The cost of making the Larger can =
=$0.324
A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.
Do you mean the ratio 1:2
For question 4 the answer is yes and for question 5 the answer is false
