Surface area of a cylinder = 2 x Pi x r^2 + 2 x Pi x r x h
R = 27 cm
H = 37 cm
Take away the Pi seeing as you want to keep it in terms of Pi
2 x 27^2 + 2 x 27 x 37 = 3456 Pi cm^2
Your answer is B
Answer:
The mean number of customers that will arrive in a five-minute period is 2.
Step-by-step explanation:
a. What is the mean or expected number of customers that will arrive in a five-minute period
For one minute, the mean is of 0.4 customers.
So, using proportions, for 5 minutes, the mean is of 5*0.4 = 2 customers.
The mean number of customers that will arrive in a five-minute period is 2.
You divide the fractions to get percents
Elena's total cost (C) is 5(9.98 + 24.99 + x)
Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:
Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)
C = 5(9.98 + 24.99 + x)
Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)
