From what I can pick up from your problem statement, you want to know "<span>a similar charm has a diameter of 4 cm what is the circumference." Please, would you use proper punctuation in your writing, for greater clarity:
"A</span><span> similar charm has a diameter of 4 cm. What is the circumference?"
The formula for the circumference of a circle, when the diameter is known, is
C=</span>
d or C=pi*d
In this case, with diamter 4 cm, the circumference, C, is 4pi cm.

You need to use the binomial probability formula:
where:
n = total number of events = 10
k = number of events we are testing = 6
p = probability of event happening = 0.5
= 210×0.015625×0.0625
= 0.205078
Hence, the probability of getting 6 boys out of 10 births is p = 0.205.
