What is the volume of a cylinder with a radius of 7 feet and a height of 12 feet? Use 3.14 for pi. Round your answer to the near

mylen [45]

Given :-

Radius of cylinder is 7ft.
Height is 12ft .

To Find :-

The volume of the cylinder .

Solution :-

As we know that the volume of the cylinder is ,

$\longrightarrow$ Volume = πr²h

On substituting the respective values ,

$\longrightarrow$ Volume = 3.14 * (7ft)²*12ft

$\longrightarrow$ Volume = 3.14*49ft²*12ft

$\longrightarrow$ Volume = 1846.32 ft.³

Hence the required answer is 1846.32 ft³.

Line segments JK and JL in the xy-coordinate plane both have a common endpoint J(-4,11) and midpoints at M, (2, 16) and M2 (-3,5

ohaa [14]

Answer:

12.1

Step-by-step explanation:

We use the formula for the distance between two arbitrary points $(x_1,y_1)$ and $(x_2,y_2)$ in the xy-coordinate plane, that is:

$d=\sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}$

So, replacing the points $M=(2,16)$ and $M_2=(-3,5)$ , we obtain:

$d=\sqrt{(2-(-3))^2 + (16-5)^2}\\d=\sqrt{(2+3)^2 + (16-5)^2}\\d=\sqrt{5^2 + 11^2}\\d=\sqrt{146 }=12.083045... \simeq 12.1$

that is the answer.

note: observe that we only use the coordinates between the two midpoints and not the point J.

What is the value of x in the equation 3x - 4 (2x - 5) = 15

Zepler [3.9K]

Hey there! I'm happy to help!

Here is our equation

3x - 4 (2x - 5) = 15

First, we will sue the distributive property to remove the parentheses. The term outside the parentheses is -4, so that is what we multiply the insides by.

3x-8x+20=15

We combine our like terms (our x-values).

-5x+20=15

We subtract 20 from both sides.

-5x=-5

We divide both sides by -5.

x=1

Have a wonderful day and keep on learning! :D
