Radius=r=15ft
Height=h=120ft

$\\ \tt\Rrightarrow V=\pi r^2h$

$\\ \tt\Rrightarrow V=\dfrac{22}{7}(15)^2(120)$

$\\ \tt\Rrightarrow V=\dfrac{22}{7}(225)(120)$

$\\ \tt\Rrightarrow V=42390ft^3$

Answer:

42390 ft³

Step-by-step explanation:

Since the tanks are congruent, they both have same volume.

If you rejoin them, it will form a cylinder with the radius of 15 ft and height of 120 ft.

<u>The volume of the cylinder:</u>

V = πr²h = 3.14*15²*120 = 84780 ft³

<u>The volume of each tank is half the volume of the cylinder:</u>

V(tank) = 84780 / 2 = 42390 ft³

I will give lot of points please help

Answer:

V = 43323 mm³

(second answer is already correct)

Step-by-step explanation:

these pennies make up the shape of a cylinder, so, we can solve this question by solving for the volume of a cylinder.

the volume of a cylinder can be found with the formula:

V = πr²h

(V = volume ; π = pi ; r = radius ; h = height)

We know the diameter of this cylinder is 19.05 mm. Diameter is two times the length of the radius, (diameter is all the way across, radius is from center to outer / halfway across) meaning that we can find the radius by dividing 19.05 by 2.

diameter = 19.05

radius = 19.05 / 2 = 9.525

so, r = 9.525

we also are given the height of this cylinder, 38 mm

so, h = 38

π = 3.14159 (π is a constant)

plugging our measurements into the volume formula:

V = πr²h

V = (3.14159)(9.525²)(38)

V = (3.14159)(362.9025)(38)

V = 43323.4894628

[rounded to V = 43323 mm³]

And yes, the volume is not affected by a change in shape. (you are correct)

hope this helps!!

Which is the slope of the line that passes through the points (3,5) and (8,7)?

Hatshy [7]

Hi there!

»»————-　★　————-««

I believe your answer is:

$m=\boxed{\frac{2}{5}}$

»»————-　★　————-««

Here’s why:

The formula for the slope of two given lines given is 'rise over run'.

⸻⸻⸻⸻

$\boxed{\text{Slope Formula:}}\\\\\frac{y_2-y_1}{x_2-x_1}\\\\\rightarrow (x_1,y_1),(x_2,x_1) - \text{Two Points Given}$

⸻⸻⸻⸻

We are given the points (3,5) and (8,7).

⸻⸻⸻⸻

$\boxed{\text{Finding the Slope:}}\\\\\rightarrow m=\frac{7-5}{8-3}\\\\\rightarrow \boxed{m=\frac{2}{5}}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Which composition of transformations maps figure EFGH to figure E"F"G"H"?

Lady bird [3.3K]

The transformations would map EFGH to ${\text{E''F''G''H''}}$ is a reflection across line k followed by a translation down. Option (a) is correct.

Further explanation:

Given:

The compositions of transformations from EFGH to ${\text{E''F''G''H''}}$ are as follows,

(a). A reflection across line k followed by a translation down.

(b). A translation down followed by a reflection across line k.

(c). A ${180^ \circ }$ rotation about point G followed by a translation to the right.

(d). A translation to the right followed by a ${180^ \circ }$ rotation about point G.

Explanation:

Translation can be defined as to move the function to a certain displacement. If the points of a line or any objects are moved in the same direction it is a translation.

Rotation is defined as a movement around its own axis. A circular movement is a rotation.

The transformations would map EFGH to ${\text{E''F''G''H''}}$ is a reflection across line k followed by a translation down. Option (a) is correct.

Option (a) is correct.

Option (b) is not correct.

Option (c) is not correct.
