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.
A radius is half of a diameter. Example Diameter:4 Radius:2
The diameter of a circle is twice its radius.
It is half of the diameter or radius = diameter/2
diameter = 30 units area = 225*pi square units
The given measure, 225*pi cm is a linear measure so it cannot refer to the area. It could refer to the radius or the circumference of the circles, or the length of an arc or a segment of the circle. It could, of course refer to something else, but then the task of finding the diameter is near impossible. If it is the length of an arc or a segment, you require further information. Since that is not provided, perhaps one can assume that the measure does not refer to either. That leaves the radius or the circumference. If the radius is 225*pi then the diameter is simply 2*radius = 450*pi cm. If the circumference is 225*pi, then the diameter is circumference/pi = 225 cm.
Radius = Diameter/2 Diameter = 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

radius = diameter/2
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
A radius is half of a diameter. Example Diameter:4 Radius:2
pi * 225/4 Radius is 15/2 pi r2 = pi * (15/2)2 = pi * 225/4
The diameter of a circle is twice its radius.
the radius is one-half the diameter radius = diameter/2 diameter = 2 x radius
