Expert Answer:

x2 + y2 = 8x and y2 = 4x
x2 + 4x = 8x
x2 - 4x = 0
x(x - 4) = 0 
x = 0 to x = 4
Required area = begin mathsize 16px style integral subscript 0 superscript 4 square root of 8 straight x minus straight x squared end root dx minus integral subscript 0 superscript 4 square root of 4 straight x end root dx end style
Integrate it further.
