Answer:
18.84 inches.
Step-by-step explanation:
Volume = 4/3 π r^3 = 113.04
r^3 = 113.04 / 4/3 * 3.14
r^3 = 27
r = 3 inches,
So the circumference = 2 * 3.14 * 3
= 18.84 inches.

It is given that getting boy or girl is equally likely. The chance of getting boy or girl on birth is 1/2
P(Boy) = P(Girl) =0.5
If a couple plans to have 8 children then probability of getting at least one girl is
P(Al least one girl out of 8 children) = 1 - P(No girl in 8 children)
= 1 - P( Getting all boys in 8 children)
= 1 - (0.5)^8
= 1 - 0.0039
P(At least one girl out of 8 children) = 0.9961
The probability of getting at least one girl out of 8 children is 0.9961.
The probability 0.9961 is high enough for the couple to be very confident that they will get at least one girl in 8 children
