cones

Posted by Kurt on October 07, 2002 at 10:16:59:

A disk has a V cut to the centre and rolled and sealed into a cone.
The cutout V is also rolled into a cone and sealed.
What would the angle of the V be in order that the sum of the volumes of the two cones be a maximum?.

Thank you in advance.
