Answer:

Step-by-step explanation:
-This is a binomial probability distribution problem.
-Given that p=0.86 and n=11, the sample variance can be calculated using the formula:

#We substitute the given parameters in the formula to solve for variance:

Hence, the sample variance is 1.32
Answer:
A=πr2
A=π8^2
A=π* 8* 8
A= 64π
A= 64x3.14
A= 200.96 in^2
