16. The radius is half of the circumference. So you would multiply the radius by two.

Wrong!
Circumference is 2*pi*radius = 50.27, approx.

The circumference of a circle with an 8 cm radius is: 50.27 cm
The circumference of a circle with a radius of 8 meters is: 50.27 meters (r x 2 x Pi = circumference).

radius of a circle = 4 inchesFormulas:Circumference of a circle = 2π radiusradius =circumference/2π=8π/2π=8/2= 4
A circle with a radius of 8 units has a circumference of 50.27 units.The circumference will be 16 pi or 50.2655 (about). Circumference, the distance around a circle, is pi times diameter or it's pi times twice the radius.C = 2 * pi * r = 2 * pi * 8 = 16 * pi
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
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.
Circumference = 2*pi*radius So Radius = Circumference/(2*pi) = 8/(2*pi) = 4/pi = 1.2732 (to 4 dp)
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
If the radius of the circle is 8 cm the circumference is: about 50.27 cm (r x 2 x pi = circumference).
Circumference = (pi) x (diameter) Diameter = 2 x radius
A circle with a radius of 8 inches has a circumference of 50.27 inches.
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.
