The radius of a circle with a circumference of 36cm is: 5.729 cm
2.7
It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
you multiply the diameter by pi which is approximately 3.14
A circle of radius r has a circumference of 2*Pi*r and an area of Pi*r*r, where Pi is the constant which is approximately 3.14159. Use the first equation to calculate the radius and then the second to calculate the area.

Circumference is the enclosing boundary of a curved geometric figure, especially a circle. Radius is a straight line from the center to the circumference of a circle or sphere. Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.
A circle of radius r has a circumference of 2*Pi*r and an area of Pi*r*r, where Pi is the constant which is approximately 3.14159. Use the first equation to calculate the radius and then the second to calculate the area.
A = 38.52 cm2
The diameter is 36/pi
circumference = 12*pi = 37.699 yards to 3 decimal places
The radius of the circle.
