1 solution: the flower bed with the largest area is needed, so 16m first limits the flower bed diameter, that is, the flower bed diameter is16m and the flower bed circumference is16 * 3.14 = 50.24m..

(1) Outside area of flower bed = perimeter * height = 50.24 * 0.3 (m2) =15.072m2.

(2) Flower bed volume = bottom area * height = 3.14 * (16/2) * (16/2) * 0.3 = 60.288 cubic meters.

A: Yes. . . . . .

2 solution: cone volume = low area * height /3 (the specific algorithm involves calculus)

Cylindrical volume = bottom area * height

From the meaning of the title, the volume and bottom area of the two are the same.

Cylindrical water level = conical water level /3 = 4cm.

A: Yes. . . . . .
