Diameter is 10 inches.
The answer depends on what part of the circle measures 25.25 inches.
If a circle measures 83 inches in circumference the diameter is: about 26.42 inches. You can easily do this calculation for other circles by dividing the circumference by Pi (about 3.1416).
It means that the statement is referring to a circle or a sphere whose diameter measures 12 inches.
39 inches / pi = 12.4 inches
The radius (not raduis) is 8 inches.
Circumference of the circle: 23*pi = 72.257 inches rounded up to 3 decimal places
The ratio between the diameter of a circle and its circumference is constant: π. A circle whose circumference measures 3 feet has a diameter of 3/π feet: approximately 11.459 inches.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
The straight-line measurement from one point to another through the origin of a circle is the diameter of the circle.
The square because its perimeter is 16 inches while the circumference of the circle is 15.708 inches.
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.
