r=radius d=diameter r=d/2 r=2/2 r=1 meter
The radius of a circle is 1/2 of the diameter.
It is the centre of the circle. The size of the radius makes no difference.
a radius is half the diameter of a circle
diameter = 4.4/pi cm
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.

The radius of a circle is 1/2 of the diameter.
It is the centre of the circle. The size of the radius makes no difference.
a radius is half the diameter of a circle
diameter = 4.4/pi cm
A circle has a constant radius whereas an oval does not.
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.

radius is half and diameter is the whole Expanding theabove statement: Diameter is the width of a circle; Radius is one half the width. In math, the radius refers to the distance from the centerpoint of a circle out to the edge.
The radius of the circle.
The formula for the circumference, (C) of a circle is C = 2πr.....where r is the radius. Let R be the radius of the larger circle and r the radius of the smaller circle. Then 66 = 2πR - 2πr = 2π(R - r) Then R - r = 66/2π = 33/π ≅ 10.504 The difference between the two radii is 10.504 (3dp)
