  1. A = 4πrh

  2. A = 2πr(r + h)

  3. A = 2πrh

  4. A = πr2h

C Correct answer
Explanation

The lateral surface area of a cylinder is the area of the side, which is the circumference of the base multiplied by the height. This is given by 2*pi*r*h.

AI explanation

The lateral surface area of a cylinder is calculated using the formula 2 pi r h. Substituting the given variables A, r, and h into this formula yields the relationship A equals 2 pi r h.
