I need some help with my script please.

radius = r; {

if (radius != 1)

throw invalid_argument("Invalid value for radius");

else

setRadius(r);

}

}

double getRadius() {

return radius;

}

double getArea() {

return pi * radius*radius;

}

double getDiameter() {

return 2 * radius;

}

double getCircumference() {

return 2 * pi*radius;

}

};
