Answer:

[tex]r = 5[/tex] --- Radius

[tex]h = 3.9[/tex] --- Height

Step-by-step explanation:

Given

Shape: Cone

[tex]Volume = 97in^3[/tex]

Required

Determine different possible values of radius and height

The volume (V) of a cone is calculated as:

[tex]V = \frac{1}{3}\pi r^2h[/tex]

Substitute 97 for V

[tex]97 = \frac{1}{3}\pi r^2h[/tex]

Multiply both sides by 3

[tex]3 * 97 = \frac{1}{3}\pi r^2h*3[/tex]

[tex]291 = \pi r^2h[/tex]

Take [tex]\pi[/tex] as 3.14

[tex]291 = 3.14* r^2h[/tex]

Divide both sides by 3.14

[tex]\frac{291}{3.14} = \frac{3.14* r^2h}{3.14}[/tex]

[tex]\frac{291}{3.14} = r^2h[/tex]

[tex]92.68 = r^2h[/tex]

From the question, we understand that:

[tex]r \ne h[/tex]

So, we have to assume a value for either r or h and then solve for the other variable.

Let [tex]r = 5[/tex]

So, We have:

[tex]96.28 = 5^2 * h[/tex]

[tex]96.28 = 25 * h[/tex]

Make h the subject

[tex]h = \frac{96.28}{25}[/tex]

[tex]h = 3.8512[/tex]

[tex]h = 3.9[/tex] --- approximated

Note that there are other different possible values of h that is true for

[tex]92.68 = r^2h[/tex] where [tex]r \ne h[/tex]

Step-by-step explanation:

Answer:

31 tests.

Step-by-step explanation:

The rate for the grading is 10.5 every 30 minutes.

Two 45 minute prep periods are 90 minutes.

90 / 30 = 3.

Since three 30 minute periods fit into 90 minutes, we get

3 x 10.5 = 31.5 tests.

Since a teacher did not finish grading the .5 of the test, we don't count it.

Our answer is 31 tests.

Answer:

Yes you are correct.

Step-by-step explanation:

Answer:

Year 1 and 2

36%

Step-by-step explanation:

Given the data :

Year ______1 ___ 2 ____ 3 ___ 4

Students __ 14 __ 19 ___ 25 __ 33

Greatest growth is observed between year 1 and 2

Growth percent :

(year 2 - year 1) / year 1 * 100%

(19 - 14) / 14 * 100%

5 / 14 * 100%

0.3571 * 100%

= 35. 71%

= 36%

The growth percent between year 1 and 2 is greater than between the other years

Year 2 and 3 = (6/19) * 100% = 31.57%

Year 3 and 4 = (8/25) * 100% = 32%

Answer:

1 and 2 x=32%

Step-by-step explanation:

1. 5/14=x/100

2. 500/14=14x/14

so you get 36%

Answer:

78.6m of fencing

That would cost $982.50

Step-by-step explanation:

Perimeter: 2(22.7)+2(16.6)=P

P = 78.6

Cost: 78.6*12.50

C = 982.50

Answer:

24-(L times 2) then divide the awnser by 2

Step-by-step explanation:

Answer:

2(l+b)

2*4+2*b=24

2b=24-8

2b is 16 so b is 16/2

Answer:

Approximately 15.05 ft

Step-by-step explanation:

You need to use tangent for this question.

Since tan θ = [tex]\frac{Opposite}{Adjacent}[/tex]

to find the Opposite, we need to rearrange the equation to:

Adjacent × tan θ = Opposite.

So if you insert 62 for θ and 8 feet for Adjacent, you will get:

8 × tan(62) = Opposite.

and you will get approximately 15.05 feet for your Opposite side

The answer for the first equation x + 5y = 0 is,

[tex]x = - 5y[/tex]

Diameter of the circle in the middle = 8 ft

Radius of the circle in the middle :

[tex] =\tt \: \frac{Diameter }{2} [/tex]

[tex] =\tt \frac{8}{2} [/tex]

[tex] =\tt 4 \: ft[/tex]

Thus, the radius of the circle in the middle = 4 ft

Area of the entire circle :

[tex] =\tt \pi {r}^{2} [/tex]

[tex] = \tt3.14 \times 4 + 6 \times 4 + 6[/tex]

[tex] = \tt3.14 \times 10 \times 10[/tex]

[tex] =\tt 3.14 \times 100[/tex]

[tex]\color{plum} = \tt314 \: ft[/tex]

Thus, the area of the entire circle = 314 ft

Area of the circle in the middle :

[tex] =\tt \pi {r}^{2} [/tex]

[tex] =\tt 3.14 \times 4 \times 4[/tex]

[tex] = \tt3.14 \times 16[/tex]

[tex]\color{plum} =\tt 50.24 \: ft[/tex]

Thus, the area of the circle in the middle = 50.24 ft

Area of the shaded portion :

= Total area of the figure - Area of the circle in middle

[tex] =\tt 314 - 50.24[/tex]

[tex]\color{plum} =\tt 263.76 \: ft[/tex]

▪︎Therefore, the area of the shaded portion = 263.76 ft
