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.
