Answer
For each part, I'll have 3 surfaces, viz., One outer surface that is the part of the bigger sphere; two identical surfaces where each is a semicircle of radius r.
surface area of outer surface = 4πr^2/4 = πr^2
Surface are of two identical semicircular regions = 2*πr^2/2 = πr^2.
So, surface area of each part = 2πr^2.
Total surface area of all four parts = 8πr^2.
