Acone is filled to a height of 3 inches with a liquid. the liquid is then poured into an empty cylinder with the same height and same radius as the cone. what is the height reached by the liquid in the cylinder?

1 inch

Volume of the cylinder = πr²h

Volume of the cone = 1/3πr²h

If the radius are the same for both the cone and the cylinder, then the liquid will reach 1/3 of its height in the cylinder compared to the cone. 

Height = 1/3 x 3 inches 
Height = 1 inch


The height of the cylinder will be 1 inch.

It would be 15 m how i got the answer: (20x20) + b^2 = (25x25)400 + b^2 = 625625-400=225square that and get 15hope this : )
