two cylindrical jars, A and B, have diameters 2X cm and 5X cm respectively,
initially, B is empty and A contains water to depth of 20 cm.
If all the water in A is poured into B, find the height of the water in jar B.
:
Change the diameters to radii, x and 2.5x
:
Let h = depth of water in B
;
The volume remains the same, write a volume equation
B vol = A vol
=
=
divide both sides by , results:
6.25h = 20
h =
h = 3.2 cm is the depth in B
