Try this:
public static double circleArea (double r){
double area = 0;
if (r>=0){
area = Math.PI *Math.pow(r , 2.0);
}
return area;
}
or this:
public static double circleArea (double r){
if (r>=0){
return Math.PI *Math.pow(r , 2.0);
}
return 0;
}
Your area variable has scope within the {} brackets which is why you have a problem compiling the return area; which is after the closing }.
