how do i find the perimeter of a circle

The perimeter of a circle is called the circumference and can be found with the formula C=Dpie. D=Diameter. Circumference=Diameter x pie. I do believe that pie equals close to 3.14.

The perimeter of a circle is the CIRCUMFERENCE, C of the circle.
C = Ï D where D is the diameter of the circle
Also, since D= 2 Ï r where r is the radius of the circle,
C = 2 Ï r

the perimeter of a circle is (2 x pi x radius) or (pi x diameter)
pi is approximately 22/7 (if u havent got a calculator)

2 x Pi X the radius or Pi x the diameter. Pi = 3.1416
