This is a Korean CSAT mathematics multiple-choice problem. Solve it and put only the correct choice symbol, one of ①, ②, ③, ④, ⑤, inside \boxed{}.
Problem 27 Consider a right circular cylinder whose two bases are congruent circlesC 1 andC 2, each of radius 5. On the circleC 1 (the bottom base), there are two pointsAandBsuch that AB= 5. On the circleC 2 (the top base), there are two pointsCandDsuch that CD= 3. It is given that AD= BC. LetHbe the foot of the perpendicular fromDto the plane ofC 1. If the area of quadrilateralABCDis four times the area of triangleABH, find the height of the cylinder. [3 points] ①3 √ 2 ② √ 19 ③2 √ 5 ④ √ 21 ⑤ √ 22
