I'm really bad with story problems and I can't seem to figure this out....

Question

Story problems are the worst because I can't infer what the question is really asking me, please help! :/ I think I have to figure out how to do a problem along with joint variation but there's so many different numbers I don't know which ones to use.

 

The weight of a can of baked beans varies jointly as the height and the square of the diameter of the can. If a 4-inch-high can with a 3-inch diameter weighs 14.5 ounces, then what is the weight of a 5-inch-high can with a diameter of 6 inches?

Answer 1

varies jointly means ...

[z] = [x][y][k] 

x,y are variables

k is a constant that you'll probably need to find

z is what you're ultimately interested in finding

 

 

 

[WEIGHT] = [HEIGHT] *[SQUARE of DIA] * [Unknown Constant]

[weight] = [height]*[dia^2]*[k]
