Here is a variation of an earlier problem.
A sphere of diameter D has a point P internally and from this point 4 lines radiate to the circumference.
These lines are equi-angular at P.
The 4 solid sectors thus formed are 1/5,1/4,1/3,13/60 ths. of the total volume.
Find the distance from P to the centre of the sphere.
