If a circle has a diameter of 19, the circumference is: 59.7 (diameter x Pi = circumference)
If the diameter of a circle is 9 the circumference is: 28.3
If a circle has a diameter of 5 the circumference is: 31.4
If a circle has a diameter of 2.25, the circumference is: 7.069
The diameter of a circle is the straight-line distance across the circle, passing through its center. If the diameter is given as 120 cm, then the diameter is simply 120 cm. If you meant the circumference or radius instead, please clarify!

Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
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 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.
