Answer:
The formula for 'h' is
.
The height of the cylinder is 3 in.
Step-by-step explanation:
Given,
Surface Area of Cylinder = 251.2 sq. in.
Radius = 5 in
We have to find out the height of the cylinder.
Solution,
We know that the Surface area of cylinder is given as;

Here 'r' is the radius and 'h' is the height.
We have to solve this for 'h'.

Hence The formula for 'h' is
.
Now we solve for 'h'.
Since 
On putting the given values, we get;

Hence The height of the cylinder is 3 in.
When taking the composite of two functions, the resulting domain is the more restrictive of the two original domains. g(x) has a domain of all real numbers, but f(x) has a domain of x=/= 2. So, the domain of f(g(x)) is x=/= 2
