Answer:
20
Step-by-step explanation:
The area of a circle is equal to pi*radius^2
We can then write this as
314.1592=π*r^2
We then divide pi to get
100=r^2
take the square root and you find that the radius equals around 10
The diameter is always equal to the radius times two which means that the diameter is 20
hope this helps
Answer:
The required probability is 0.55404.
Step-by-step explanation:
Consider the provided information.
The number of typographical errors on a page of the first booklet is a Poisson random variable with mean 0.2. The number of typographical errors on a page of second booklet is a Poisson random variable with mean 0.3.
Average error for 7 pages booklet and 5 pages booklet series is:
λ = 0.2×7 + 0.3×5 = 2.9
According to Poisson distribution: 
Where
is average number of events.
The probability of more than 2 typographical errors in the two booklets in total is:

Substitute the respective values in the above formula.



Hence, the required probability is 0.55404.
