The Volume of this cone, revolved about the y-axis, in terms of constants r,h and variable y is:
Equation of the line following the Hypotenuse:
f(y) = -((yr - hr) / h)
I then found (f(y))^2 and used the washer method to find:
V = -pi [[A] - [B]]
A = [ (r^2)(y^2) / 3(h^2) ] (Limits: 0 & h)
B = [ ((rh)^2)(y) / (h^2) ] (Limits: 0 & h)
I just started Volumes of rotation. Someone want to check?Why are you doing volumes of rotation?Why not? This thread turned into one of mathematics and caps. I thought I'd contribute to the further understanding that hat. Plus I missed out on the challenge.
