Two perpendicular planes intersect a sphere in two circles. These circles intersect in two points spaced 14 cm apart, measured along the straight line connecting them. If the radii of the two circles are 18 cm and 25 cm, what is the radius of the sphere?

There's a typo:
sqrt(753/2) should be sqrt(753)/2
The calculated value is correct, as it represents the latter formula.
