When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.

Radius is one-half of the diameter of a circle. Therefore, the radius of an eight-inch diameter circle is four inches. The diameter of a circle is a straight line joining a point on the circumference through the centre to the 'opposite' point on the circumference.

Diameter = 2*Radius

The radius of a circle is half its diameter (the measure of the circle from one side across to the other).

The diameter of a circle is the length of a straight line drawn through the center of the circle to its edges.Or, measure the circumference of the circle and divide by pi (3.14159).Or you can multiply the radius times twoTo get diameter you have to find the radius and then double it to get the diameter

radius = diameter/2

Radius = 1/2 of diameter = 7/2 = 3.5 inches

Circumference of a circle = pi*diameter or 2*pi*radius

Radius = Diameter/2 so if diameter = 20 Radius = 20/2 = 10

The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius

diameter is 2 times the radius 24

Diameter = 2*Radius

The radius is half the diameter.

Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
