Let dv be an element in the form of a disk that cuts through the cone.

the radius of the disk is (r / H) X.

the volume euals the area of the  disk times the thickness.

dv = Pi[(r / H ) X] ^2
Now Intergate From 0 To H

X' = Int (x dv) / Int dv = 3/4 H...........PLEASE RATE ME IF U SATISFIED........
