x= $12.30 if you need that too
Given:
Radius of a cylinder = 5 units.
Surface area of the cylinder = 
To find:
The height of the right cylinder.
Solution:
Surface area of a cylinder is:

Where, r is radius and h is the height of the cylinder.
Putting
in the above formula, we get



Subtract
from both sides.


Divide both sides by
.


Therefore, the height of the cylinder is 11 units.
