Convert for loop with cells and polyarea into a cellfun function

Hi, I was wondering if it would be possible to convert those lines of code of the for loop into the same expression but using the function cellfun
for i = 1 : length(dataOUT)
area(i,1) = polyarea(dataOUT{i}(:,1),dataOUT{i}(:,2));
end
[~,idx_cluster] = max(area);
Just for this example, dataOUT could be:
p = linspace(0,2.*pi,9);
x = 1.2*cos(p)';
y = 1.2*sin(p)';
dataOUT{1}(:,1) = x;
dataOUT{1}(:,2) = y;

area = cellfun(@(DO) polyarea(DO(:,1), DO(:,2)), dataOut);
