Answer:

169.646003294, hope this helps

Step-by-step explanation:

To solve this equation,

A= 2\pi rh+2\pi r^{2}

Since the radius is 3 meters. We know what r is. A radius of a circle or sphere is any of the line segments from its center to the perimeter. The height is 6 meters.

A=2\pi (3)*6+2\pi (3^2)\\ A=2\pi (18)+2\pi 9\\ A=113.097...+2\pi 9\\ A=113.097+56.548...\\ A=169.64600...

Sorry, I don't feel like writing all the numbers in and also it would cut out later on.

A random sample of 250 juniors majoring in psychology or communication at a large university is selected. These students are ask
fenix001 [56]

Solution :

It is given that :

Number of students in a random sample majoring in communication or psychology at an university = 250

Total number of students majoring in psychology = 100

Number of students majoring in psychology  those who are happy = 80

So number of students majoring in psychology  those who are not happy = 20

Total number of students majoring in communication = 250 - 100 = 150

Number of students majoring in communication  those who are happy = 115

So number of students majoring in psychology  those who are not happy = 35

a). Probability of the students happy with their major choices are

    $=\frac{80+115}{250}$

    = 0.78

b). Psychology major $=\frac{80+20}{250}$

                                   = 0.4

c). Probability of the students who are happy with the communication as the choice of major = $\frac{115}{250}$ = 0.46

d). Students unhappy with their choice of major given that the student is psychology major = $\frac{20}{250}$  =  0.018
