A circumference of 62.8cm
10
The radius (not raduis!) is 3.183 cm, approx.
Multiply the diameter by pi, which is approximately 3.14.
If the circumference is 20 cm then the diameter is 6.366 cm

The formula for the circumference of a circle is C = 2πr, where C is circumference, π is pi (approx. 3.142), and r is the radius. So, for a circle with a radius of 6cm, C = 2(3.142)(6cm) = 18.852cm Rounding to the proper number of significant figures, this answer would be 20cm.
