Dennis has three identical cylinders filled with water. How many cones should he be able to fill with the water if the cones have the same radius and the same height as the cylinders?

3 cylinder will fill 9 cones with water

Step-by-step explanation:

This problem bothers on mensuration of slides, cone and cylinder

We know that the

Volume of a cylinder = πr²h

Volume of a cone = 1/3(πr²h)

Given that both cylinder and cone has same height and radius

From the given expression we can deduce that the cone is 3 times smaller than the cylinder in volume

So if 1 cylinder will fill 3 cones

Then 3 cylinders will fill x cones

By cross multiplication we have

x= 3*3cones

x= 9 cones

Hence 3 cylinder will fill 9 cones with water

9 cones

Step-by-step explanation:

The formula to find a volume of a cylinder is:

V1 = pi*r^2*h

Where r is the base radius and h is the height

The formula to find a volume of a cone is:

V2 = (1/3)*pi*r^2*h

So, if they have the same base radius and same height, we have that:

V1/V2 = 1/(1/3) = 3

The volume of the cylinder is 3 times bigger than the volume of the cone, so each cylinder of water can fill 3 cones.

Is Dennis has 3 cylinders, he is able to fill 3*3 = 9 cones with water.
