How to get the answer?

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.

Putting some effort in is usually the first thing needed to get the answer!

I tried for over two days but i didn't get it :(

Share what you have done so far.

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

arrRadius = [5,3.5,6];%Random radii

sic!
