Could someone give me a hint:
I have a right circular cone with a slant hieght of 3 a radius of r and a hight of h.
I want to know what angle "o"(between the perpendicular height and the slant hieght) will maximize the volume.
/|\
/o| \
/ | \
I know that O = tan-1 ( r/h) or r / sqrt(9-r^2)
But I am having trouble relating this to the volume of the cone, or if i am even on the right track using an inverse trig.
Thank you,
