Answer:2592/25
Step-by-step explanation: Big circle is pi*r^2= (4+3+3)^2*pi =314.15 minus 4^2*pi=50.26 equals 263.89. the big circle minus the first 2 layers of the circle = the outer circle. 314.15-(4+3)^2*pi=160.21 263.89-160.21=2592/25

Step-by-step explanation:
 
        
                    
             
        
        
        
To express the height as a function of the volume and the radius, we are going to use the volume formula for a cylinder: 

where

 is the volume 

 is the radius 

 is the height 
We know for our problem that the cylindrical can is to contain 500cm^3 when full, so the volume of our cylinder is 500cm^3. In other words: 

. We also know that the radius is r cm and height is h cm, so 

 and 

. Lets replace the values in our formula:





Next, we are going to use the formula for the area of a cylinder: 

where

 is the area 

 is the radius 

 is the height
We know from our previous calculation that 

, so lets replace that value in our area formula:



By the commutative property of addition, we can conclude that:
