A cylindrical container with a bottom diameter of 30 cm and a height of 8 cm is filled with water, and then the water is poured into a cylindrical container with a bottom diameter of 10 cm. How high is the water in the cylindrical container?
Suppose the height of water in a cylindrical container with a bottom diameter of 10 cm is h cm, then according to the meaning of the title, we get π × (30 △ 2) 2 × 8 = π × (10 △ 2) 2 × h, and the solution is h = 72. A: the water in a cylindrical container with a bottom diameter of 10 cm is 72 cm high

There is a cylindrical cup with a ground diameter of 8 cm, which contains water. Put a small cone with a bottom diameter of 2 cm into the small cone, and the height of the water rises from 16 cm to 17 cm?
Volume of small cone = volume of water rise = (17-16) * 3.14 * 4 ^ 2 = 50.24
Height of small cone = 3 * 50.24 / (3.14 * 1 ^ 2) = 48
