Question

Type the correct answer in the box. Write your answer as a whole number.The radius of the base of a cylinder is 10 cm, and its height is 20 cm. Colon is used to fill the cylinder with water. The radius of the cone base is 5 cm, and its height is 10 cm. The number of times one needs to use the completely filled colon to completely fill the cylinder with water is *blank*

Answer 1

Answer: 24 times

Explanation:

volume of cone: (1/3)×5^2×π×10=250π/3 cm^3

volume of cylinder: 10^2×π×20=2000π cm^3

2000π/(250π/3 )=2000π×(3/250π)=24
