It is very easy math!
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
The diameter of a circle if the circumference is 41 cm is about 13.05 cm (C divided by Pi = diameter)
A circle with a radius of 81 cm has a circumference of 508.94 cm
If the circumference of a circle is 45 cm the length of the diameter in centimeters is: about 14.32 cm
circumference = π x diameter ⇒ diameter = circumference ÷ π = 12 cm ÷ π ~= 3.8 cm
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
If 15 cm is the diameter then circumference is pie x diameter which is 3.14 x15
A circle with a radius (d/2) of 15 cm has a circumference of 94.2 cm
566cm
circumference = 15*pi = 47.124 cm rounded to 3 dp
The diameter of a circle when the circumference is 35 cm is: 11.14 cm (circumference divided by Pi = diameter).
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
The diameter of a circle with a circumference of 45 cm is: about 14.32 cm
The circumference of a circle with a diameter of 12 cm is: about 37.7 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
The circumference of a circle with the diameter of 2.7 cm is 8.5 cm
