1) the area of the "side" of the cylinder is A1= pi (4 in).
2) the total area of the circular ends of the cyl. is A2 = 2 pi (2 in)^2 (since the radius of the cyl. is 2 in).

The desired total surface area is A = A1 + A2.  Keep "pi;" do not substitute a numerical value for "pi."

PLEASE ANSWER ASAP
STatiana [176]

Answer:

2/9 is the correct option.

Step-by-step explanation:

As the spinner is numbered 2, 4 and 5

The general formula for probability :

P(A) = n(A) / n(S)

n(S) is the number of whole states occur in two spins which is 3 × 3 = 9

n(A) is the event that Rico will get a product of 20.

n(A) = 2   ∵ 4 × 5 and 5 × 4 will bring the product 20.

Therefor, the probability that Rico will get a product of 20 when Rico spins the spinner twice will be:

P(A) = n(A) / n(S)

       = 2/9

Therefore, 2/9 is the correct option.

Since the number of days in July and in August is the same, there is no need to work out on the total number per month.

The mean number of people per day in August = 160 + 20 = 180
