A cylindrical medicine bottle with an inner diameter of 8 cm and a liquid medicine depth of 10 cm is exactly three fifths of the bottle's capacity. How many cubic centimeters is the volume of a spherical medicine bottle?
The radius is
8 △ 2 = 4 (CM)
How much is the potion
4 × 4 × 3.14 × 10 = 502.4 (cm3)
What is the volume of the bottle
502.4 △ 3 / 5 = 837.3 (cm3)
3.2 liters of liquid medicine in 60 ml bottles, at least () bottles are required
At least 54 bottles. 3.2 liters is 3200 ml, 60 ml bottles. After 53 bottles are filled, there are 2 ml left, so 54 bottles should be filled
A cylindrical medicine bottle, the inner bottom diameter is 8 cm, the depth of the liquid medicine is 15 cm, which just accounts for three-quarters of the whole cup capacity
（8/2）²*3.14*5=753.6（cm³）
753.6 / three quarters = 100.48 (ML)
