Answer:

V≈83.78

Step-by-step explanation:

The formula to find the volume of a cone is V=πr(squared) h/3

Steps

V= π (4)^2  5/3

V= π (16)  1.66666666667

V = 50.2654824574 * 1.66666666667

v= 83.7758040958

Round

V = 83.78

Answer:

The volume of cone is 83.73m³.

Step-by-step explanation:

To find the volume of the cone we use Formula:

[tex] \sf V = \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: \frac{1}{3} \times 3.14 \times {4}^{2} \times 5 \\ \\ \implies \frac{1}{3} \times 15.70\times 16 \\ \\ \implies \: \frac{1}{ \cancel3} \times \cancel{251.20} \\ \\ \implies \sf \pink{83.73 {m}^{3} }[/tex]

Hence, the volume of cone is 83.73m³.

Answer:

C

Step-by-step explanation:

There are 140 women in the 5% sample. to find an estimate of all the women we can multiply but by 20. 5% x 20 = 100%. 140 x 20 = 2,800.

Answer: A) c=10x

Step-by-step explanation:

because im to smart and add then multiply 10=c

Answer:

4. Multiply both sides by -2 => x - 7 = -36, Add 7 to both sides -> x = -29

5. Add 12 to both sides => 28 = 1/4x, then multiply both sides by 4 => 112

x = 112

7. Multiply both sides by 3 => 5x - 2 = 63, add 2 to both sides => 5x = 65,

Divide both sides by 5 -> x = 13

10. Multiply both sides by 6 => 132 = 3x - 6, Add 6 to both sides => 138 = 3x,

Divide both sides by 3 => x = 46

Answer:

I think it's 9156.24 but it's been a long time since I did this

Answer:

9,156.24

divide the 108/2 to get the radius

108/2=54

square 54

54x54=2916

multipy that by 3.14

3.14x2,916=9,156.24

Answer:

the MAD to this set is 6.75

Step-by-step explanation:

The process is pretty long on how to find the MAD but here it goes.First you find the mean of the set( 70 )then you find the distances between all the numbers and the mean( 68 is 2 values away from being 70 so that would be 2) than you add all the distances together than divide that number by the amount of values are in the set.

hope that makes sense have a good day

Step-by-step explanation

Answer:

199.51$

Step-by-step explanation:

10 x 12 = 120$

25 x 5 = 125$

5 x 8 = 40¢

1 x 11 = 11¢

30 + 50 = 80$

120$ + 125$ + 40¢ + 11¢ + 80$ = 325.51$

325.51$ - 44$ = 281.51$ - 25$ = 256.51$ - 12$ = 244.51$ - 15$ = 229.51$ - 30$ = 199.51$

Answer:

I believe it's the first one

Answer:

The First one and the third one

Step-by-step explanation:

All you have to do is the distributive property and multiply 7 times 3x and 7 times 2 to get 21x + 14. Then you add like terms for the third one and get x2+5.

Answer:

the square of a negative number always be positive

eg: -2² = -2×-2 = (-×- = +) +4

Answer:

A and C are congruent.

Step-by-step explanation:

Answer:

The trapezoids and the irregular figures at the top left.

Step-by-step explanation:

Congruent means "in agreement or harmony." So that means in math congruent means "the same" and the trapeziods were both the same and so were the irregular figures.

Answer:

[tex]v=\pi r^{2} h\\213= 3.14 *r^{2} *8.6\\213=27.004*r^{2} \\213/27.004=r^{2} \\7.9=r^{2} \\r=\sqrt{7.9} \\r=2.81[/tex]

Answer:

128

Step-by-step explanation:

The area of the larger rectangle is \begin{align*}8(16)=128 \ \mathrm{units}^2\end{align*} and the area of the smaller rectangle is \begin{align*}5(10)=50 \ \mathrm{units}^2.\end{align*} If we compare the areas in a ratio, it is \begin{align*}50:128 \ = \ 25:64 \ = \ 5^2:8^2.\end{align*}

Answer:

84 months

Step-by-step explanation:

Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.

12 * 7 = 84

Maria is 84 months old

Answer:

Maria is 84 months old.

Multiply the years(y) by every 12 months that pass(m).

[tex]y * m = 84[/tex]

note that y is 7, and m is 12, because we count every 12 months that pass for 7 years.
