Asked by Harriet

A cylindrical container has a diameter of 14cm and a height of 20cm and is full of water. A student pours the water into another cylinder of diameter 20cm. How deep is the water in the second cylinder?
Answered by oobleck
V = Bh where B=πr^2
So, the ratio of heights is the inverse of the square of the ratio of diameters: (14/20)^2 making the height
(14/20)^2 * 20 = 9.8cm
Answered by henry2,
V = pi*r^2*h = 3.14*7^2*20 = 3079 cm^3 of water.

pi*r^2*h = 3079
3.14*10^2*h = 3079
h = 9.8 cm = depth of water.

15 liters of water are poured into a cylinder of diameter 20 cm. Use the value 3.14 for Pi to find how deep the water is in the cylinder.
