Answer:

11 meters

Step-by-step explanation:

Use the formula:

$V = \pi r^{2} h$

V = 7599, h = 20, π = 3.14

Plugin the numbers and solve for r

$7599=3.14(20)r^{2} \\7599=62.8r^{2} \\7599/62.5=62.8r^{2} /62.8\\121=r^{2} \\\sqrt{121}=\sqrt{r^{2} } \\r=11$

Find the volume of the triangular prism

Otrada [13]

Answer:

1,848

Step-by-step explanation:

$volume = ( \frac{1}{2} \times a \times b) \times h \\ = ( \frac{1}{2} \times 7 \times 24) \times 22 \\ divide \: 2 \: and \: 24 \: by \: 2 \\ = (1 \times 7 \times 12) \times 22 \\ = (84) \times 22 \\ = 1,848 \\ volume \: = 1,848$

MULTIPLE CHOICE HELP ASAP! Brainliest for correct answer.

N76 [4]

Answer:

An equation of the circle with centre (-2,1) and radius 3 is $\mathbf{(x+2)^2+(x-1)^2=9}$

Option D is correct.

Step-by-step explanation:

Looking at the figure we get centre of circle C (-2,1) and radius of circle r = 3

The equation of circle is of form: $(x-h)^2+(x-k)^2=r^2$ where (h,k) is centre and r is radius.

We have centre C (-2,1) so, we have h = -2 and k = 1

We have radius = 3 so, r = 3

Putting values in the equation and finding the required equation:

$(x-h)^2+(x-k)^2=r^2\\(x-(-2))^2+(x-1)^2=(3)^2\\(x+2)^2+(x-1)^2=9$

So, an equation of the circle with centre (-2,1) and radius 3 is $\mathbf{(x+2)^2+(x-1)^2=9}$

Option D is correct.

In the Fig., if ABCD is a parallelogram, then the value of x is

Natalija [7]

Answer:

Value of x is 20.

Step-by-step explanation:

The angle opposite to 4x is also 4x.

Similarly, the angle opposite to 5x is also 5x.

So, 4x+4x+5x+5x=360

18x=360

x=360/18

x=20

ben earned 45 dollars mowing lawns. he worked 3.2 hours on monday and 4.3 hours on tuesday. how much did he earn per hour?

dlinn [17]

Answer:

6 dollars per hour

Step-by-step explanation:

We can set up and solve an equation to answer this question. For this problem, let x stand for the amount he earned per hour. The equation that represents this situation is 3.2x + 4.3x = 45. The first term represents monday and the second represents tuesday. When these add up they should equal 45 because that is the total amount he made. To find his pay per hour, solve for x.

First, combine the like terms

7.5x=45

Next, divide both sides by 7.5

x=6
