This function computes the area of a circle based on the parameter r. write a script. This script asks the user to type r1 for circle 1, and r2 for circle 2. Then display areas of circle 1 and circle 2. And display which area is bigger, or they are equal. The script should call function CircleArea ().

The formula is missing from your comment, and without the formula, your comment does not appear to be guidenace to solve the question that was asked in 2014.

Function:
function [area] = CircleArea(radius)
area = pi * radius^2;
script:
rad1 = input('Enter Radius of Circle 1');
area1 = CircleArea(rad1);
disp(['Area of Circle1 = ' num2str(area1)])
rad2 = input('Enter Radius of Circle 2');
area2 = CircleArea(rad2);
disp(['Area of Circle2 = ' num2str(area2)])
if(area1 > area2)
disp('Area of Circle1 is greater than area of Circle2');
elseif (area1 < area2)
disp('Area of Circle1 is less than area of Circle2');
else
disp('Area of Circle1 is equal to area of Circle2');
end
