Explanation:

- The curved surface area (CSA) of a cylinder is given by the formula: \(CSA = 2\pi rh\).

- You're told that the CSA is 2200 cm². So, \(2\pi rh = 2200\).

- The circumference of the base of the cylinder is given by: \(C = 2\pi r = 110\).

Now, let's solve for height \(h\):

1. From the circumference equation:

$$ r = \frac{110}{2\pi} $$

2. Substitute \(r\) in the CSA formula:

$$ 2\pi \left(\frac{110}{2\pi}\right) h = 2200 $$

3. Simplify and solve for \(h\):

$$ 110h = 2200 $$

$$ h = \frac{2200}{110} $$

$$ h = 20 $$
