pi = 21.99/7 pi = circumference/diameter Just multiply your diameter by pi to get a circumference.
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x pi = circumference).
The circumference of any circle is (pi) x (the circle's diameter).
If a circle has a circumference of 6 inches the diameter is: 1.91 inches (circumference divided by Pi = diameter).
If the circumference of a circle is 10 inches, the diameter is: about 3.183 inches. (circumference divided by Pi = diameter)
circumference of a circle = 2*pi*radius or diameter*pi
A circumference of 21.99 cm
Assuming that what you mean is that the diameter is 7cm...Pi x 7 = 21.99114858C = 22
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
C=2 pi R
3.14
7cm; the diameter of a circle is twice its radius.
Diameter of a circle = circumference/pi
Diameter of a circle = circumference/pi
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
The radius is 7cm
A circle with a circumference of 11.25 has a diameter of: 3.581
