Solve double intergral ?

For example , i have this double intergral :

I tried this code : >>S = x+y+sqrt(100-x^2-y^2) >>M= int(S,y,0,sqrt(100-x^2)) >>M1=int(M,x,0,10) But Matlab returns me the same int(...) i just typed, not the answer

Answer 1

sol=integral2(@(x,y)x+y+sqrt(100-x.^2-y.^2),0,10,0,@(x)sqrt(100-x.^2))

Best wishes
