Circumference is (pi x diameter of circle). (Diameter is the distance across the circle, going through the very centre. It is also twice the radius, which is the distance from the middle of the circle to the outer edge). In the question you don't indicate what the 14cm is (i.e. diameter/radius ?), so I can't work it out for you.
The area of a circle with a 14 cm radius is: 615.8 cm2
Diameter = 14/pi cm
112cm2
14 cm
It is 14 cm.
The area of a circle with a 14 cm radius is: 615.8 cm2
14 cm. The diameter is just the radius times 2.
14 cm
The answer depends on what measurement "14 cm" refers to.
Diameter = 14/pi cm
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.

14 cm
It is 14 cm.
14 cm. In a circle, diameter is always twice the radius.
The circumference of a circle with an 81.6 cm diameter is: 256.4 cm
14 pi cm
