When you cut the sphere by three perpendicular planes passing through the centre of the sphere, you get 8 pieces.
Consider one piece,
The curved surface is (1/8)th of the total surface of the sphere = 4πr^2/8 = πr^2/2
The three plane surfaces are quadrants of a circle = 3*πr^2/4
In terms of the radius the total surface area of each piece = πr^2/2 + 3*πr^2/4
= πr^2[(1/2)+(3/4)]
=(5/4)πr^2.
