Aim:
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);
> radius: 11.45 circumference: 71.9425 area: 411.8707
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!");
