The volume of a cylinder is:

where
is the radius and
is the height.
The height is 4 inches greater that the radius, so:

Substituting this in the formula for volume:

the volume is 
thus:

Dividing everything between pi:


We can see that the solution for this is 
since 
We have the radius, now we find the height:


Answer:
20
Step-by-step explanation:
16=1 2/10R + -8
