Answer:

the volume of the hemisphere is 1970.2 cubic inches.

Step-by-step explanation:

The given is,

                  Radius of hemisphere is 9.8 inches.

Step:1

                 Formula of volume of hemisphere is,

                             ..................(1)

                 Where,

                           r - Radius of hemisphere

Step:2

                 From the given,

                          r = 9.8 inches

                 Equation (1) becomes,

                                                 =  

                                                 =                    

                                                 = (0.66666666)(3.1415)(942.192)  

                                                 = 1971.23

          Volume of hemisphere = 1971.23 cubic inches

Result:is 1970.2 cubic inches.

Answer:

1971.2

Step-by-step explanation:

I just did it and got it right, it's not 1970.2, trust me

The straight line distance between the submarine and the airplane is 4000 feet.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Let d represent the straight line distance between the submarine and the airplane. Hence:

sin(30) = 2000/d

d = 4000 feet

The straight line distance between the submarine and the airplane is 4000 feet.

Answer:

15 boys selected

Step-by-step explanation:

Given

[tex]N =11000[/tex] --- The population

[tex]n = 100[/tex] --- The sample selected

[tex]p =0.152[/tex] -- The proportion of boys

Required

The expected number of boys selected

The expected number is calculated by multiplying the sample size by the proportion of boys.

So, we have:

[tex]Boys = p * n[/tex]

[tex]Boys = 0.152 * 100[/tex]

[tex]Boys = 15.2[/tex]

[tex]Boys = 15[/tex] --- approximated
