Click come see full answer. Similarly, the is asked, what is one of 9 customs circle?
The circumference is 9 or roughly 28.26 inches.
Subsequently, concern is, exactly how do you figure out circumference from diameter? The circumference = π x the diameter that the circle (Pi multiplied by the diameter of the circle). Just divide the circumference by π and you will have the size of the diameter. The diameter is just the radius times two, so division the diameter by two and you will have the radius of the circle!
