// 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. // // Your code starts after this line radius = 11.45; circumference = 2 * PI * radius; area = PI * radius * radius; // 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!");
