Homework Statement
A right circular cone has height 6 cm and base radius 2. It is over-filled with ice cream,
in the usual way. Place the cone so its vertex is at the origin, and its axis lies along the
positive y–axis, and take the cross-section containing the x–axis. The top of this crosssection
is a piece of the parabola y = 8 − x2 . The whole filled ice-cream cone is obtained
by rotating this cross-section about the y–axis.
What is the volume of the ice cream?
Homework Equations
The Attempt at a Solution
So for I have
x2 = 8-y
v = pi . integral((8-y)dx) from 0 to 8
I am not sure if I am on the right path though.
Many thanks,
