The circumference of a circle with a radius of 2 is: 12.57 units.
It will have a radius of 2 because 2*pi*radius is the circumference of the circle.
Radius of a circle = circumference/2*pi
The circumference of a circle if the radius is 2 feet is: about 12.57 feet.
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
For a circle, circumference = 2 x pi x radius.
Circumference of a circle = 2*pi*radius or diameter*pi
The ratio of the circumference to the radius of the circle is 2 times pi
Radius of a circle = circumference/(2*pi)
Radius of a circle = circumference/2*pi
int radius = 2; int output; radius = radius * 2; output = radius * Math.PI; Console.WriteLine(output);
Circumference of a circle = 2*pi*radius Circumference = 2*pi*5.6 = 35.18583772 units
