The radius of any circle is the straight line distance from the centre of the circle to any point on the circumference of the circle.
The radius being 21 cm makes no difference to the definition of the radius; it just means that the straight line distance from the centre of that circle is 21cm away from any point on the circumference of that circle.
The radius of a circle with a radius of 21 cm is 21 cm.
