The number of times one needs to use the completely filled cone to completely fill the cylinder with water is

Step-by-step explanation:

Given that there is a cone and cylinder with equal radius and height.

Recall volume formula for cone and cylinder as

Volume of cone =

Volume of cylinder =

Thus we find that cylinder has a greater volume and ratio is 3:1

Hence 3 times if filled up with a cone the cylinder will be completely full

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
