The answer depends on what measurement "14 cm" refers to.
14 cm. The diameter is just the radius times 2.
Area = pi*142
A circle with a radius of 7.7 cm has a circumference of 48.38 cm
A circle with a radius of 208 cm has a circumference of 1306.9 cm
A circle with a radius of 9.2 cm has a circumference of 57.81 cm
The area of a circle with a 14 cm radius is: 615.8 cm2
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
14 cm. In a circle, diameter is always twice the radius.
14 cm
It is 14 cm.
14 pi cm
14 cm. The diameter is just the radius times 2.
28 pi cm, about 88 cm
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The area is 616 cm2
Area = pi*142
