They are not the same. Diameter is twice the size as radius.
No because the radius of a circle is half of its diameter.
The length of a radius of a circle is half of the diameter of the same circle. So, diameter is always twice the radius.
diameter to radius ratio (for same circle) is 2:1
The radius is half the diameter.

you cant: pi is the same for any circle - 3.1415... the diamter or the radius has to be given diameter divided by two equals the radius the radius times two equals the diameter
the diameter divided by 2
Radius = Diameter/2 Diameter = 2* Radius
A radius is a straight line from the circumference (boundary) of a circle to the centre. A diameter is a straight line that goes from the circumference to the centre and then continues until it reaches the circumference of the other side. In a circle, all points on the circumference are the same distance from the centre. As a result, the second part of the diameter is the same as the first. In other words, diameter = radius + radius = 2*radius.
to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius
The circumference is the distance AROUND a circle. The diameter is the distance ACROSS a circle. The radius is the the distance FROM THE CENTER of the circle (same thing as one-half of the diameter).
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
