What is the diameter of a full circle?
Diameter: the longest distance from one end of a circle to the other. The diameter = 2 × radius (d = 2r).
How do you find the diameter of a circle in inches?
Divide the circumference by pi, approximately 3.14, to calculate the diameter of the circle. For example, if the circumference equals 56.52 inches, divide 56.52 by 3.14 to get a diameter of 18 inches. Multiply the radius by 2 to find the diameter.
How do you convert diameter to radius?
Just divide by two; half the diameter is the radius. For example, if you have a diameter of 6cm, just divide by 2. You will get half of the value, which is 3cm; this is the radius.
What is the diameter of 2 inches?
