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:
x^2-2x+1
f(x)=x^2
g(x)=x-1
f(g(x))=f(x-1)=(x-1)^2=x^2-2x+1
