The circumference of a circle with an 8 cm radius is: 50.27 cm
If the radius of a circle is 8 feet the circumference is about 50.27 feet.
A circle with a radius of 8 inches has a circumference of 50.27 inches.
If the radius of the circle is 8 cm the circumference is: about 50.27 cm (r x 2 x pi = circumference).
A circle with a radius of 8 inches has a circumference of 50.27 inches.
A circle with a radius of 8 units has a circumference of 50.3 units.
The circumference of a circle with a radius of 8 meters is: 50.27 meters (r x 2 x Pi = circumference).
The circumference will be 50.27
The radius is 1.27

Circumference of a circle = 2*pi*radius = 8*pi or 25.13274123 units
The circumference of a circle can be found with this formula: Circumference = 2*(radius)*∏ where ∏ can be rounded to 3.14 Plugging in your radius of 4: Circumference = 2*4*∏ = 8*∏ which is around 25.13.
