The diameter is the same regardless of the measurement scale used. The diameter is the largest dimension across a circle passing through the center.
Also, the diameter is twice the radius. Where the radius is the measurement from the center to the outer edge.
Given that the circumference of a circle is found as: C = 2 * pi * r
It can be found that the diameter is: D = C / pi
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
If the area of a circle is about 28 square inches the diameter of the circle is: about 6 inches (5.971).
The area of a circle that has a diameter of 14 inches is: 153.9 square inches.
The area of a circle with a diameter of 16 inches is: 201.1 square inches.
The area of a circle with a diameter of 75 inches is: 4,418 square inches.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
If the circumference of a circle is 62.8 inches the diameter is: 20 inches.
The circumference of a circle with a diameter of 3 inches is 9.425 inches.
The circumference of a circle when the diameter is 17 inches is: 53 inches.
The circumference of a circle that has a diameter of 35 inches is 109.96 inches.
The circumference of a circle with the diameter 11 inches is 34.56 inches.
The circumference of a circle with a diameter of 45 inches is 141.37 inches.
If the area of a circle is about 28 square inches the diameter of the circle is: about 6 inches (5.971).
The diameter is double the radius of a circle. So you get 5 inches for the diameter.
The circumference of a circle, if the diameter is 9.5 inches, is: 29.85 inches (diameter x Pi = circumference)
If the circumference of a circle is 28 inches the diameter is: 8.913 inches (circumference divided by Pi = diameter).
The diameter of a circle with circumference of 25.56 inches is: 8.136 inches (diameter x Pi = circumference).
