Answer: option b; 34.54 cm
Explanation:
The circumference of a circle is given by:
C = 2*pi*r
where r is the radius of the circle, and pi is the irrational constant:
pi = 3.14...
In this problem, we know that the diameter of the circle is equal to 11 cm
We also know that the relation between the diameter and the radius of a circle is given by:
d = 2r
So the equation of the circumference may be written as:
C = 2r*pi = d*pi = 11cm* 3.14 = 34.54cm
So the right option is B.
