Hello, I have a problem I cant solve. Need assistance! You cut out a piece of a circle (like you cut a piece of a cake), then make a cone by joining the edges of what remains of the circle. What angle must the "cakepiece" have to maximize the volume of the resulting cone? I know the cone Volume is V = pi*r^2h/3, and I need to derive this to get maxpoints. Cant figure out how though? question 2. this time, we also make a cone out of the piece we cut out. What angle must this piece have to maximize the volume of BOTH the cones made? Please point me in the right direction if you will. Thanx a lot!
