Circular diameter is the distance from side to side of a circle through the middle.
The distance from side to side through the center of the Earth is called the diameter. The Earth's diameter is 12,742 kilometers.
The distance from one side of a circle to the other going through the center is called the Diameter, the distance from any side to the center (half the diameter) is called the radius.
Because the radius is the distance from one side to the center, and the diameter is the direct distance from one side to the other through the center.
The Diameter is the distance from one side of the circle all the way to the other side. The Radius is half the distance in a circle. Simply put: 40cm = Diameter 20cm = Radius (Half the distance) :)
diameter
The diameter of something is the distance across it - perhaps you are thinking of the unit of length the decimetre, which is equal to 10 centimetres.
The diameter is the distance from one side of the circle, through the middle, and to the other side. It is a straight line. It is equal to The circumference (the distance around the circle) divided by pi (about 3.1415926536)
Diameter- A line going straight from side to side of a circle, equals the total distance across the circle. Radius- Half of the total diameter. For example, if the diameter is 8, the radius is 4.
The mathematical equation which describes how to measure the distance from Earth to the moon using Earth's diameter as a unit of measure is d = Dcot(p/2)/2 Where d is the distance from Earth to the moon, D is the diameter of the Earth and p is the angle of parallax subtended at moon by the diameter of the Earth.
a diameter is not a unit of measurement; it is the distance across a circle.
A decimetre is a metric unit for measuring distance. A diameter is a characteristic of a circle or similar shapes.
