The conical surface extends to a horizontal distance up to 4,000 ft at which slope ratio?

Explanation:
Slope ratio tells you how far you must go horizontally for each unit of vertical change. A 20:1 ratio means 20 units of horizontal distance for every 1 unit of rise. If the conical surface reaches 4,000 ft horizontally, the vertical rise is 4,000 ÷ 20 = 200 ft. So the 20:1 ratio matches that horizontal extent. Using other ratios would yield different heights for the same 4,000 ft horizontal distance (for example, 10:1 would give 400 ft rise, 15:1 about 266.7 ft, 25:1 about 160 ft), which is why 20:1 is the appropriate slope ratio here.
