The perimeter of a circle is equal to pi times the diameter, so for a circle with a diameter of 14 cm, multiply by pi, which is approximately 3.14, and you get 43.96 cm, which for most purposes you could round off to 44 cm.
The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
The area of a circle is pi*r2 and its circumference is 2*pi*r where r is the radius = half the diameter. So r = 3.5 cm. Then area = 38.48 square cm and circumference = 21.99 cm As to the circumstance of the circle, that is rather a personal question!
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
Diameter of a circle = circumference/pi Diameter of a circle = 2*radius
7cm; the diameter of a circle is twice its radius.
3.5 cm
A = 38.485 cm2
Assuming that what you mean is that the diameter is 7cm...Pi x 7 = 21.99114858C = 22
circumference of a circle = 2*pi*radius or diameter*pi
A circumference of 21.99 cm
It depends on what the 7 cm measure refers to.
pi = 21.99/7 pi = circumference/diameter Just multiply your diameter by pi to get a circumference.
C=2 pi R

The circumference of a circle with a 7cm radius is 44cm. The area is 154cm2
If a cylinder's height is 7cm and its area is 659.73cm2, its diameter will be approximately 14.66cm
