The radius multiplied by 2 => 2r
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 or multiply by 2 the radius
The diameter is double (two times) the radius, no matter what the radius is.
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
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.
The radius would be 9 meters because the diameter is double the radius.
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
You double the radius.. if the radius is 10 the diameter is 20.
The radius is double the diameter so 4cm.
