There are four points P, a, B, C on the sphere, PA, Pb, PC are perpendicular, PA = 3, Pb = 4, PC = 5, so how to calculate the sphere area?

In cuboid apbq-cdef, PA, Pb and PC are perpendicular and all the vertices are on the sphere
Then the diameter of the ball is the diagonal of the cuboid
D^2=3^2+4^2+5^2=50
D = 5 times, followed by 2 times
S=4πR^2=πD^2=50π
