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.

What does the 24 inches represent??? The radus, the diameter, or the distance around the circular edge, which is the circumferenbce.
The circumference of a 24 foot diameter circle is about 758.4 feet. (C = d x Pi)
Circumference of a circle = 2*pi*radius or diameter*pi
Diameter = 12 inches, Circumference = 12*(pi) = approx. 37.699 Radius = 12 inches, Circumference = 2*12*(pi) = 24*(pi) = approx. 75.398 inches If the author has actually measured the outside of the circle (i.e. the perimeter of a dinner plate), that is the circumference! Problem solved.
If a circle has a diameter of 24 inches its circumference is: 75.4 inches (diameter x Pi = circumference).
Well, darling, if a circle has a circumference of 24 inches, we can use the formula C = 2πr to find the radius. Just plug in 24 for C and solve for r. You'll find that the radius of this sassy circle is 3.82 inches.
