~Hello There!~
The formula to find the area of a circle is:
We already know this answer, so we write it as:
We need to calculate the radius (r) from this so divide both sides by
Square root this to get r
r = 3.949327085
The formula for circumference is
(d is the diameter )
Double the radius to get the diameter:
d = 7.89865417
Multiply this value by to get the answer
The circumference is 24.81435391
Hope This Helps You!
Good Luck :)
Have A Great Day ^_^

Answer:
c. normal probability distribution
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
By the Central Limit Theorem, it is a normal distribution, so option c.
