really!? Its 6 cm!

The area of a circle with radius r is pi*r*r where pi = 3.1416 approx. When r = 6 cm, the area is 113.1 sq cm.
Circumference of the circle: 2*pi*6 = 37.699 cm to three decimal places
r = 1.38 cm
The circumference of a circle if the if the radius is 6 cm is: 37.7 cm
If the diameter is 12 cm the radius is 6 cm.
If the diameter is what you are talking about that is 6 cm, you must divide that number by two to find the radius because the radius is half a diameter. The radius of a circle with a diameter of 6 cm. would be 3 cm.
Radius of a circle is half of its diameter and so 12/2 = 6 cm
6 cm. The radius is 1/2 of the diameter.

6/2 = a radius of 3 cm
If it is a 7.1 cm radius circle, then its radius is exactly 7.1 cm!
The area of a circle with radius r is pi*r*r where pi = 3.1416 approx. When r = 6 cm, the area is 113.1 sq cm.
Circumference of the circle: 2*pi*6 = 37.699 cm to three decimal places
The radius of the circle is: 9.549 cm
