Suppose that you want to design a cylinder with the same volume as a given cylinder but you want to use a diff radius and height
Anton [14]

Answer:

Yes, r and h can be changed to produce same volume by;

Increasing "r" and decreasing "h" or by decreasing "r" and increasing "h".

Step-by-step explanation:

What the question is simply asking is if we can get same volume of a particular cylinder if we change the radius and height.

Now, volume of a cylinder is;

V = πr²h

Now, for the volume to remain the same, if we increase "r", it means we have to decrease "h", likewise, if we decrease "r", we now have to increase "h".

In how many months will the total cost of both options be the same? What will that cost be?
gregori [183]
If you make yourself a monthly expense chart:
                                                       Months
                    <u>  1       2            3           4        5        6       7      8        9        10</u>
Opt 1         -80      -30        -30        -30      -30     -30    -30    -30   -30      -30
Opt 2         -40     -40        -40        -40       -40      -40    -40    -40    -40   -40

By month 5 the total amount spent for Opt 1 is $200 and Opt 2 is $200

For part two add up the values for each all the way up to month 9.
Option 1:   80 + 30(8) =  80 + 240 = 320 spent
Option 2:   40(9)  = 360  spent

So option 1 is cheaper by month 9
