Question 273139: hi. can you help me to solve this problem.? thanks a lot
A propane tank is constructed by welding hemispheres to the ends of a right circular cylinder. Write the volume V of the tank as a function of r and l, where r is the radius of the cylinder and hemispheres, and l is the length of the cylinder.
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
The volume of a sphere of radius 
is given by:
Each hemisphere is half of that volume, but you have two hemispheres, so you have one whole sphere.
The volume of a cylinder with radius and length 
is:
The total volume is the sum of the two:
\ =\ \frac{4}{3}\pi r^3\ +\ \pi r^2l)
Which can be left as it is or manipulated as desired. I would use:
\ =\ \pi r^2\left(\frac{4}{3}r\ +\ l\right))
or perhaps
\ =\ \frac{\pi r^2}{3}\left(4r\ +\ 3l\right))
