How to Revolve a 2D Profile and Make it's 3D Plot

Hello, i am trying to figure out how to revolve this profile around any axis (lets assume x=35) and make the plot in 3D. I found a really good solution here (https://www.mathworks.com/matlabcentral/answers/522502-how-can-i-revolve-a-2d-plot-by-2pi-around-an-axis-to-make-a-3d-surface-plot) but i am having trouble applying to this simple code

x = [82,80,65,38,82]

y = [82,54,36,94,82]

plot(x,y)

This is a example:

x = [82,80,65,38,82];
y = [82,54,36,94,82];

x_zero = 35;

theta = linspace(0,2*pi,100);

X = [];
Y = [];
Z = [];
for i = 1 : length(x)
    X_new = sin(theta)*(x(i)-x_zero)+x_zero;
    Y_new = cos(theta)*(x(i)-x_zero)+x_zero;
    Z_new = y(i)*ones(1,100);
    X = [X ; X_new];
    Y = [Y ; Y_new];
    Z = [Z ; Z_new];
end

surface(X, Y , Z)

You may modify x and y, and the function surface may not be appropriate！
