Question 165082
A sphere with a radius(x - 1) / 2 is floating in a cylindrical tank of water with radius (x – 1).  Determine the volume, V,  of water in the tank. The height of the cylinder is (x + 4) / 6 Express your answer as a polynomial in factored form.  Leave your answer in exact form.
===========================
The volume of the tank is PI*(r^2)*h
V = PI*[(x-1)^2]*(x+4)/6
V = (PI/6)*(x-1)*(x-1)*(x+4)  (in factored form)
I don't know what "a polynomial in factored form" means.
===========================
The amount of water displaced by the sphere can't be determined without additional info, such as its density, or what part of it is submerged.
