The circumference of a circle that has a diameter of 8 inches is 25.12 inches.
How do you find the circumference of an 8ft circle?
Pre-Algebra Examples
The circumference of a circle is equal to Pi π times the diameter d . Since the diameter d is equal to 2 times the radius r , the formula for circumference using radius is 2πr 2 π r .
How do you find the diameter of a 8 inch circle?
To calculate the diameter of a circle, multiply the radius by 2. If you don’t have the radius, divide the circumference of the circle by π to get the diameter.
What is the circumference of an 8 inch round cake?
