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.
