If the diameter of a circle is 3mm the circumference is: 9.424 mm
Use the equation C = pi*d Substitute C = 3.14 * 25 C = 78.5 ft NB This is only an approximate value, because '3.14' is only an approximate valuer for 'pi' , but convenient to use. The other eq'n to use is C = 2 pi r Where 2r = d ( two radii equals one diameter ) . NB . 'radii' is the common noun plural of 'radius'. NOT 'radiuses'.
Use the equation C = pi d Algebraically, rearrange d = C / pi Substitute d = 11.25 units /3.14 d = 3.5828..... d ~ 3.58 units.
If a circle has a diameter of 14, the circumference is: 43.98.
The diameter of a circle with a circumference of 18 is: 5.73
If a circle has a circumference of 26 the diameter is: 8.276
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
C = ~18.85 mm
If a circle has a diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)
The circumference of any circle is (pi) x (its diameter). If diameter = 1 then Circumference = pi .
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
Use the equation C = pi*d Substitute C = 3.14 * 25 C = 78.5 ft NB This is only an approximate value, because '3.14' is only an approximate valuer for 'pi' , but convenient to use.

The circumference of a circle with a diameter of 25 is: 78.54
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 14, the circumference is: 43.98.
If a circle has a diameter of 2.25, the circumference is: 7.069
