Answer:
18.152866242 = h
Explanation:
The curved surface area of a cylinder is calculated using the formula, curved surface area of cylinder = 2πrh, where 'r' is the radius and 'h' is the height of the cylinder.
1368 = 2(3.14)(12)(h)
1368 = 75.36(h)
1368/75.36 = h
18.152866242 = h
Round as necessary.
