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 equiangular 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.
