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.
Answer:
D)
Step-by-step explanation:
All sides are congruent because all sides are the same.

OK, the square root of 250 is 15.811 . . .
but since this can't be expressed as a decimal for your purposes, let's try factoring. Since 250 ends in a zero, only numbers 5 or 0 or those ending in 5 or 0 could be factors.
The square root of 250 can be factored into the square root of 25 and the square root of 10.
The square root of 25 is exactly 5, and the exact square root of 10 is another decimal, so your simplified answer can be expressed as 5 times the square root of 10.
