To find the surface area of a cylinder, add the areas of the two circles and the rectangular piece connecting them

area of circle: A = pi(r)^2
A = pi(7)^2
A = 49pi

area of rectangle: A = length X width
the length is the circumference of the circle
C = 2pi(r)
C = 2pi(7)
C = 14pi
multiply 14 pi by the width 5
area of rectangle: 70pi

add the areas of the two circles and the rectangle:
49pi + 49pi + 70pi = 168pi

ANSWER: 168pi
for the decimal if you use pi on the calculator then the answer is 527.8
but if u multiply by 3.14 the answer is 527.5

hope this helps!

Answer:

h(6) = 32

Step-by-step explanation:

h (x) = x^2 – 4

h(6) =

Let x = 6

h (6) = 6^2 – 4

       = 36 -4

       = 32

Two families attended a baseball game. The first family bought 5 bags of popcorn and 6 souvenir cups, which totaled $65. The sec
Bumek [7]

The cost of one bag is given as

$5

<h3> How much did one bag of popcorn cost?</h3>

Generally, the equation for the First family is  mathematically given as

4x + 5y = 50

Equation  Second family:

6x + 4y = 54

We have a system of 2 equations with 2 variables.

4x + 5y = 50

6x + 4y = 54

Since we are being asked for the cost of one bag of popcorn, which we will refer to as x, we will first remove y and then proceed to find x.

Both sides of the first equation need to be multiplied by -4, and both sides of the second equation need to be multiplied by 5. We are asked for the price of 1 bag of popcorn, x, so we will eliminate y and solve for x.

-16x - 20y = -200

30x + 20y = 270

In conclusion, Simply adding the equations will get rid of y.

14x = 70

x = 70/14

x = 5

When you send out a resume, the probability of being called for an interview is 0. 40. what is the probability that the first in
Kipish [7]

The probability that the first interview occurs on the fifth resume that you sent is 0.2592.

According to the given question.

The probability of being called for an interview, p = 0.40.

So, the probability of not being called for an interview, q = 1 - 0.40 = 0.60

As we know that binomial distribution summarizes the number of trials, or observations when each trial has the same probability of attaining one particular value. The binomial distribution determines the probability of observing a specified number of successful outcomes in a specified number of trials.

Therefore, the probability that the first interview occurs on the fifth resume that you send out

= ^{5} C_{1} (0.40)^{1} (0.60)^{4}

= 5(0.40)(0.1296)

= 0.2592

Hence, the probability that the first interview occurs on the fifth resume that you sent is 0.2592.
