you have to measure the diameter of the coil and then multiply the diamter by pi
area = 9∏mm (approx. 28.26mm) circumference = 6∏mm (approx. 18.84mm)
There is a constant relationship between the radius of a circle and its circumference. This is expressed in a formula.
Because the circumference of any circle divided by its diameter is always equal to pi.
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
circumference = 15*pi cm
circumference = pi*40cm
Circ = 2 pi r, Diam = 2r so circumference = pi times diameter
100.53 inches
The circumference of a circle, if its diameter is 5.1mm, is about 16.02mm
diameter = 128/pi
The circumference = 2 x r x pi If your diamter is 81cm then your circumference is 254.5cm If your radius is 81cm then your circumference is 508.9cm
Pi is the ratio of a circle's circumference to its diamter. It equals approximately 3.14159 Pi = circumference/diameter
