The script circscript loops n times to prompt the user for the circumference of a circle (where n is a random integer). Error-checking is ignored to focus on functions in this program

circscript.m

n = randi(4);

for i = 1:n

 circ = input('Enter the circumference of the circle: ');

 [rad, area] = radarea(circ);

 dispra(rad,area)

end

radarea.m

function [radius, area] = radarea(circ)

% Calculates the radius and area of a circle,

% given the circumference

% Format of call: radarea(circumference)

% Returns the radius then area

radius = circ/(2*pi);

area = pi * radius ^2;

end

dispra.m

function dispra(radius, area)

% Prints the radius and area of a circle

% Format of call: dispra(radius, area)

% Does not return any values

fprintf('The radius of the circle is %.2f\n', radius)

fprintf('The area of the circle is %.2f\n', area)

end
