Hi, i am trying to integrate my function but when i type out my equation it gives me the wrong answer and i suspect that i may not have typed my equation properly since its long and confusing, how do i type it the equation below properly on my script?please help. The small brackets inside the bigger squareroot covers evything there and then raise to the power of 2

syms y(t)
eq=2*pi*(sqrt((y-44.56)/(-0.16))+1)*sqrt(1+((1)/(-0.32*((sqrt((y-44.56)/(-0.16))+1))+0.32))^2)

z=@(y)2*pi*(sqrt((44.56-y)/.16)+1).*sqrt(1+(1./(.32-.32*(sqrt((44.56-y)/.16)+1))).^2);
y=0:.01:10;%have no idea what you are integrating over
A=trapz(y,z(y));
