The capital pi confused me a bit, thought it was a stray character typo, should be lowercase pi.Quote:

Trick is to draw the radius of the sphere and find a right triangle, and use what you know about right triangles.
Actually i have already worked backwards and i realise that r^2 = 25-1/4h^2.Quote:

The hypotenuse is 5. It's the radius of the sphere, given in the problem statement.Quote:
