Given:

The diameter of the cylindrical pipe = 6ft.

Height of the pipe = 34 ft

To find:

The volume of the pipe.

Solution:

We have,

Diameter of cylinder = 6 ft

Radius of cylinder =\dfrac{6}{2}=3 ft

Height of the pipe = 34 ft

Volume of a cylinder is

V=\pi r^2h

Where, r is the radius and h is the height.

Putting r=3 and h=34, we get

V=\pi (3)^2(34)

V=\pi (9)(34)

V=306\pi

V=306(3.14)

V=960.84

Therefore, the volume of the cylindrical pipe is 306\pi \approx 960.84 cubic ft.

Leni [432]

The transformations which can lead to the red square image of the blue Square are; Translation, Reflection, Rotation.

<h3>What transformations lead to the image?</h3>

  • Translation is when we slide a figure in any direction. The translation of the shape can be by moving the blue leftward or rightward and the then downward.
  • Reflection is when we flip a figure over a line. The reflection involves reflect the blue Square over the line; y = x.
  • Rotation is when we rotate a figure a certain degree around a point. The rotation is by rotating the blue Square over 180⁰.

Why is it necessary to use the absolute value of the difference when finding the distance on a number line, but not necessary wh
padilas [110]
Remember that the distance on a number line is given by the formula: d=|x_{2}-x_{1}|
where 
d is the distance between the points. 
x_{2} is the second point in the number line.  
x_{1} is the first point in the number line.
Now, suppose we are trying to find the distance between the points -1 and -5; our first point is -1, so x_{1}=-1, and our second point is -5, so x_{2}=-5. Suppose we are going to find the distance between the two point without using absolute value:
d=x_{2}-x_{1}
d=-5-(-1)
d=-5+1
d=-4
Look what we have here, a negative distance! Since distances cannot be negative, we must use absolute value to always get postie distances between two point on a umber line:
d=|x_{2}-x_{1}|
d=|-5-(-1)|
d=|-5+1|
d=|-4|
d=4 

Now, the distance between two coordinates on a plane is given by the formula: d= \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2}
where
d is the distance between the two coordinates
(x_{1},y_{2}) are the coordinates of the first point
(x_{2},y_{2}) are the coordinates of the second point 
Notice that (x_{2}-x_{1})^2 and (y_{2}-y_{1})^2 are squared, so it doesn't matter if we get a negative distance because a negative number raised to an even power (like 2) is always positive; therefore we don't need absolute value in this case because we won't ever get a negative distance.

the scale from a square park to a drawing of the park is 5 m to 1 cm the actual park has an area of 1,600 m² what is the area of
ludmilkaskok [199]

Answer:

<h2>64 cm²</h2>

Step-by-step explanation:

given:

the scale from a square park to a drawing of the park is 5 m to 1 cm

the actual park has an area of 1,600 m²

find:

what is the area of the drawing of the park​

solution:

drawing scale is 5m : 1cm

<u>1,600 m² </u> = <u>      5² m²  </u>    

   x                  1² cm²

cross multiply:

5² m² x = 1600 m² (1 cm²)

x =<u> 1600 m² </u>

      5² m²

x = 64 cm²

therefore, the area of a square park in the drawing is 64 cm²

Show or describe two different ways to complete the comparison using &lt; , &gt; ,or =: 0.26 () 0.4
nordsb [41]
0.26 < 0.4
Reason: 0.26 is less than 0.4 which also can be written as 0.40.
The "mouth" points to the bigger number.
