A Correct answer
Explanation

The curved surface area of a cylinder is 2*pi*r*h. Given 4.4 = 2 * (22/7) * 0.7 * h. Simplifying, 4.4 = 2 * 22 * 0.1 * h, which is 4.4 = 4.4 * h. Thus, h = 1 m.

AI explanation

The curved surface area formula for a cylinder is 2*pi*r*h. We are given the curved surface area as 4.4, the radius as 0.7, and pi as 22/7, so the equation is 4.4 = 2 * (22/7) * 0.7 * h. Solving this gives 4.4 = 44 * 0.1 * h, which simplifies to 4.4 = 4.4h. Dividing both sides by 4.4 reveals that the height is 1 m.
