double the radius or multiply by 2 the radius
The diameter is double (two times) the radius, no matter what the radius is.
you double the radius to find the diameter.
the area doubles. for example: the radius is 2. so the area is 4pi. then double the original radius of 2 to 4 and the area is 8pi. 8pi is double 4pi.
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
The diameter is double the radius.

Double the radius
class TCircle { public: TCircle(double r = 0.00); ~TCircle(); void setRadius(const double r) { Radius = r; } double getRadius() const { return Radius; } protected: double Radius; };
Diameter = double the radius = 16

The radius would be 9 meters because the diameter is double the radius.
The radius is double the diameter so 4cm.
You double the radius.. if the radius is 10 the diameter is 20.
