What is the circumference of a 24 inch round circle?

The circumference of a circle is calculated using the formula C = πd, where C is the circumference, π is a mathematical constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter of the circle is 24 inches. Therefore, the circumference of a 24-inch round circle would be C = π * 24 = 75.398 inches.
