There is a kind of beverage bottle with a cylindrical body (excluding the bottle neck) and a volume of 30 decimeters. 3. Now there are some drinks in the bottle. The height of the drink is 20 cm when it is placed upright, and the height of the rest part is 5 cm when it is placed upside down. (see Figure) the existing drinks in the bottle are () cubic decimeters A. 20B. 21C. 22D. 24

30 × 2020 + 5 = 30 × 45 = 24 (cm3) a: there are 24 cm3 drinks in the bottle

There is a kind of drink bottle with a cylindrical body and a volume of 30 liters. Now there are some drinks in the bottle. The height of the drink is 20 cm when it is placed upright, and the rest is 5 cm when it is placed upside down. Q: how many liters of the existing drinks are in the bottle? For the detailed process, thank you

30 L = 30 cubic decimeter 20 cm = 2 decimeter 5 cm = 0.5 decimeter
Bottom area: 30 / (2 + 0.5) = 12 square decimeters
Drink in bottle: 12x2 = 24 (cubic decimeter) = 24 liters

The inside depth of a drink bottle is 27 cm, the inside diameter of the bottom is 8 cm, and the drink in the bottle is 15 cm deep. After the bottle is tightly plugged, the mouth of the bottle is inverted downward, and the drink is 20 cm deep. What is the volume of the drink bottle?

The bottom radius of beverage bottle is 8 △ 2 = 4 (CM), the volume of beverage bottle is 3.14 × 42 × [15 + (27-20)] = 50.24 × [15 + 7], = 50.24 × 22, = 1105.28 (cm3), = 1105.28 (ML); answer: the volume of beverage bottle is 1105.28 ml

The cylindrical bottle with a diameter of 30 cm and a height of 50 cm is full of drinks. Now pour the drinks into the small cylindrical cup with a diameter of 10 cm on the bottom, just pour it
20 cups, the height of the small cup?

Lonely and lonely_ Lu: the volume of cylindrical bottle: [(30 / 2) & sup2; × 3.14] × 50 = 706.5 × 50 = 35325 (cm3) the volume of a cylindrical cup: 35325 △ 20 = 1766.25 (cm3) the height of the cylindrical cup: 1766.25 △ [(10 / 2) & sup2; × 3.14] = 1766.25 △ 78.5 = 22.5 (CM
