It is important becasue the equation for the circumference is 2 times the ratio times pi.
circumference = 84*pi
Circumference of a circle = 2*pi*radius or pi*diameter.
circumference of a circle = 2*pi*radius or pi*diameter
Measure the diameter (the width) and multiply it by Pi.
Multiply the diameter by pi, and the answer will be the circumference.
Circumference of a circle = 2*pi*radius or pi*diameter
Divide the circumference by pi (~3.14) to get the diameter.
Circumference = 2 pi R = 24 piR = C / (2 pi) = (24 pi) / (2 pi) = 12
Circumfernce = 2*pi*r So 2*pi*r = 60*pi r = 30 units of length.
Circumference = pi*85 = 267.035 units of measurement to 3 decimal places
you can use 2 formulas... 2 x pi x radius or pi x diameter - dont forget that pi is always 3.14 unlsess said otherwise. :) hope this has helped.......
π is the circumference of a circle by the length of that circle's diameter. usually its circumfernce is 3.14159 to its diameter of 1 in that approximate ratio.
