// Exercise 05.01 - Variables and assignment
//
// Aim: Use variables in a calculation
//
//* Calculate the circumference and the area of a circle
//* with a given radius. Use the variables "radius", "circumference"
//* and "area". Note that when you want to try the macro for different
// values of radius, you only have to change the value of the variable
// radius instead of changing the value in each calculation.
//
// The macro language has a predefined constant PI, that you can use in your calculation.
// Your code starts after this line
radius =
circumference =
area =
// Your code ends before this line
print("radius:", radius, "circumference:", circumference, "area:", area);
// The code below is for automatically checking the result. Please ignore it!
//
ok = abs(PI*pow(circumference / (2 * PI), 2) - area) < 0.0000001;
if (ok)
showMessage("That's right. Great, you did it!");
else
showMessage("Your result is wrong! Please check your macro and try again!");
