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.
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
Radius = 24/(2*pi) = 3.8197 inches to 4 dp
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).
Circumference = 24*pi inches
The circumference of a 24-inch diameter circle is about 75.4 inches. (C = d x Pi)
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 pi*diameter Circumference = pi*24 = 75.39822369 inches
If 24 inch diameter then the C=75.36, if 24 inch radius then the C=150.72
A 12-inch diameter circle has a circumference of: 37.7
Circumference of a circle = 2*pi*radius or diameter*pi
Circumference = 24*pi = 75.398 inches to 3 dp
Radius = 24/(2*pi) = 3.8197 inches to 4 dp
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.
Circumference = 2*pi*24 = 150.796 feet to 3 dp
circumference = {pi} x diameter circumference = {pi} x 24ft ~= 75.4ft
