Diameter refers to the length of a straight line passing through the center of a circle and touching two points on its circumference.ĭiameter is equal to the length of a straight line passing through the center of a circle and touching two points on its circumference.ĭiameter is a specific type of length. The term “size in diameter” does not provide enough context. The term “diameter” represents the length of a straight line passing through the center of a circle and touching two points on its circumference.

“1 diameter” is not a standard measurement.

The diameter of a circle in inches is simply the length of a straight line passing through the center of the circle and touching two points on its circumference, measured in inches. What is the diameter of a circle in inches? Since the diameter represents the length of a straight line passing through the center of the circle, a circle with a 12 cm diameter will also have a circumference of approximately 12 cm. Since the diameter represents the length of a straight line passing through the center of the circle, a circle with a 10 cm diameter will also have a circumference of approximately 10 cm.ġ2 cm is approximately equal to 4.724 inches.

The formula to calculate the diameter is: Diameter = Circumference / π or Diameter = √(4 * Area / π).Ī circle with a diameter of 10 inches has a circumference of approximately 31.42 inches (10 inches * π).Ī circle with a diameter of 5 inches has a circumference of approximately 15.71 inches (5 inches * π).ġ0 cm is approximately equal to 3.937 inches. To calculate the diameter of a circle, you need the circumference or the area of the circle. To convert inches to diameter, you simply use the inches value as the diameter since diameter and inches represent the same length. The diameter of a circle is equal to the length of a straight line passing through the center of the circle and touching two points on its circumference.
