**jai**, Saturday, August 14, 2010 at 8:00amfirst, imagine the front view of the cone,, it should look like an inverted triangle,, then draw the content (the water - horizontal line),, note that if you draw a vertical line bisecting the inverted triangle, you actually form a right triangle,,

since you bisected it, get the radius: r= d/2 = 8/2 = 4 feet

then draw another horizontal line for which height is 2 feet,,

recall similar triangles,, you just have to do ration and proportion of the base and height,, therefore:

let x = radius when height is 2 feet

4/x=10/2

x= 4/5 or 0.8 feet

so there,, =)
