Answer 1

[Brendan Jozwiak]

func=@(x,y) sqrt(x.^2 + y.^2);
ymax=@(x) sqrt(2.*x - x.^2);
result=integral2(func,0,2,0,ymax);
disp("Result=");

Result=

disp(result);

    1.7778

Answer 2

[Torsten]

c = integral(@(x)integral(@(y)sqrt(x.^2+y.^2),0,sqrt(2*x-x.^2)),0,2,'ArrayValued',true)

c = 1.7778

syms x y
c = int(int(sqrt(x^2+y^2),y,0,sqrt(2*x-x^2)),x,0,2)

c =
