Create a function to calculate the area of three circles with different radius in your choice. use for loop to call the function and display the results as a column vector.

I created below function but still cannot understand how to disply the results as a column vector.

function Ca=Circle_area(r) 
Ca=pi*r^2;
end

I have just reused your function.

function homework()
arrRadius = [5,3.5,6];%Random radii
arrArea = zeros(size(arrRadius, 2),1);%preallocate a array (column vector)
for iLoop=1:length(arrRadius)
    arrArea(iLoop,1) = Circle_area(arrRadius(iLoop));
end
disp(arrArea);
end
function Ca=Circle_area(r)
Ca=pi*r^2;
end
