PLEASE HELP!!!!!!!!
In a water treatment plant, water passes through a cone-shaped filter with a height of 4 m and a diameter of 9 m. The water flows from the filter into a cylinder below it. One full cone-shaped filter fills one-fifth of the cylinder.

What are the dimensions of the cylinder? Use 3.14 to approximate pi.

A.
h = 3 m; r = 3 m

B.
h = 4.23 m; r = 5 m

C.
h = 15 m; r = 6 m

D.
h = 33.75 m; r = 2 m

triciaal · Answer

volume of a cylinder = pi*r^2*h
volume of a cone = 1/3*pi*r^2*h 
volume of cone = 1/3*volume of cylinder

anonymous · Answer

but i still dont know what it is

triciaal · Answer

find volume of cone from numbers given 
use ratio
volume of this cone = 1/5 the volume of this cylinder 
the diameter is twice the radius

anonymous · Answer

because this question makes no sense

triciaal · Answer

I think the radius of the cone and the cylinder should be the same but 9/2 = 4.5 not 5 unless they approximate but on second thought it should be smaller
