Oh, what a happy little question! If the radius of a circle is 5.5cm, we can find the diameter by multiplying the radius by 2. So, the diameter of this circle would be 11cm. Just a simple little calculation to bring a smile to your face!
A circumference of 34.6 cm
The radius of a circle is half of its diameter
1/2 of the diameter
The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm

Is the diameter of a circle was 11cm the radius would be 5.5cm as two radii equals a diameter.
The circumference of a circle, if the radius is 11cm, is about 69.12cm
11cm * pi 34.5575192 centimeters
C = 69.115 cm
The diameter of a circle is twice its radius
A circumference of 34.6 cm
The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.
The diameter of a circle is twice its radius
The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.
If you mean the area of a circle then it is: pi times radius squared
