hi there! im really having a hard time dealing with this problem.. hope someone can help me. i would really appreciate it..

the problem goes like this..

conical cups are to be made from a circular paper by removing a sector. by closing the remaining part of the circle, a conical cup is made. the objective is to remove the sector so that the cup is of maximum volume.

i need to come up with a program that would prompt the user to enter the radius of the circular paper. the program should then output the length of the removed sector so that the resulting cup is of maximum volume.

thank you in advance!..

And your code? And your question? Just so you know, we are not going to do it for you.
