Circumference = pi x diameter
3.5 = 3.1415 x diamater
diameter = 3.5/3.1415 =1.114 cm
A 35-cm diameter circle has a circumference of: 110 cm
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
The diameter is 23.99 cm (circumference divided by Pi = diameter).
If that's the diameter, you can multiply that by pi (which is approximately 3.14), to get the circumference.
The circumference of circle that is 8 cm is: about 25.13 cm (diameter x pi = circumference).
The diameter of a circle when the circumference is 35 cm is: 11.14 cm (circumference divided by Pi = diameter).
A 35-cm diameter circle has a circumference of: 110 cm
Diameter in cm = circumference/pi
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
The diameter is 23.99 cm (circumference divided by Pi = diameter).
The circumference of a circle with the diameter of 2.7 cm is 8.5 cm
The circumference of a circle with a diameter of 12 cm is: about 37.7 cm
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
If the circumference of a circle is 30 cm its diameter is: 9.549 cm
The circumference of a circle with a diameter of 1.3 cm is 4.08 cm
11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
