7.51

(rounded to 2 decimal places)

Step-by-step explanation:

The formula for standard deviation of binomial distribution is shown below:

Where    is the standard deviation

n is the sample size

and p is probability of success

Given n = 1000 and p =0.94, we can plug into the formula to find the standard deviation:

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a
