Step-by-step explanation:
Solution:-
- We will use the basic formulas for calculating the volumes of two solid bodies.
- The volume of a cylinder ( V_l ) is represented by:
                                   
- Similarly, the volume of cone ( V_c ) is represented by:
                                   
Where,
                r : The radius of cylinder / radius of circular base of the cone
                h : The height of the cylinder / cone
- We will investigate the correlation between the volume of each of the two bodies wit the radius ( r ). We will assume that the height of cylinder/cone as a constant.
- We will represent a proportionality of Volume ( V ) with respect to ( r ):
                                   
Where,
             C: The constant of proportionality
- Hence the proportional relation is expressed as:
 
                                  V∝ r^2
- The volume ( V ) is proportional to the square of the radius. Now we will see the effect of multiplying the radius ( r ) with a positive number ( a ) on the volume of either of the two bodies:
                                 
- Hence, we see a general rule frm above relation that multiplying the result by square of the multiple ( a^2 ) will give us the equivalent result as multiplying a multiple ( a ) with radius ( r ). 
- Hence, the relations for each of the two bodies becomes:
                               
                                           &

The sale price after both markdowns will be $336
<em><u>Explanation</u></em>
The selling price of an item is $600. After 6 months of not selling, it is marked down by 30%
So, the marked down amount after 6 months 
and the selling price after first 6 months will be: 
After another 6 months of not selling , it is further marked down by 20%. So, the marked down amount now 
Thus, the final selling price after all markdowns
