• 12л cm-
О 18 л ст-
• 216 л cm?
• 288л cm?
The correct answer is: 288 л cm²
Surface area of a cylinder = 2 * π * r * (r + h)
r = radius = 6 cm
h = height = 18 cm
Surface area = 2 * π * 6 * (6 + 18)
Surface area = 2 * π * 6 * 24
Surface area = 288 * π cm²
Surface area ≈ 288 * 3.14 ≈ 904.32 cm²
Therefore, the surface area of the cylinder is approximately 904.32 cm², which we can round off to 288 л cm².
