Please help: The base edge of a Square pyramid is 30 cm. The pyramid is 6 cm tall. Find the volume of the pyramid.

Answer:

72.25

Step-by-step explanation:

Triangles are 1/2(base x height), or (base x height) / 2.

17 x 8.5 = 144.5

144.5 / 2 = 72.25

Answer:

So the answer is 16+[(3.14)* 2)^2)

Step-by-step explanation:

4*4= 16

pie(r)^2

3.14*2^2

Area of the composite figure = 16 + 12.56 = 28.56 cm² (Option C).

Area of Composite Figure

The figure is composed of two semicircle which makes 1 full circle and a square.

Therefore, area of composite figure = area of circle + area of square.

Area of Circle = πr²

π = 3.14

r = 2 cm

Area = 3.14 × 2² = 12.56 sq. cm.

Area of Square = s²

s = 4 cm

Area = 4² = 16 cm²

Therefore, area of the composite figure = 16 + 12.56 = 28.56 cm².

Answer:

h = 12

Step-by-step explanation:

3053.63=πr^2h

Let r=9 and approximate pi as 3.14

3053.63=3.14 ( 9)^2 h

3053.63=3.14*81*h

3053.63=254.34h

Divide each side by254.34

3053.63/254.34=254.34h/254.34

12=h

Answer:

[tex] h = \dfrac{3053.63}{\pi r^2} [/tex]

Step-by-step explanation:

3053.63 = πr²h

Switch sides.

πr²h = 3053.63

Divide both sides by πr².

h = 3053.63 / πr²

An expression to determine the perimeter of a rectangle is,

⇒ Perimeter = 2 (Length + Width)

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Let the length of rectangle = x

And, The width of rectangle = y

Then, The perimeter of rectangle is defined as;

⇒ Perimeter = 2 (Length + Width)

⇒ Perimeter = 2 (x + y)

Thus, An expression to determine the perimeter of a rectangle is,

⇒ Perimeter = 2 (Length + Width)

Step-by-step explanation:

If the graph is linear then constant of proportionality is represented by slope of line.

Since, graph shows a proportional relationship.

It means that y is directly proportional to x .

So, we get                 [tex]y=mx[/tex]

Where m is proportionality constant.

Since, graph is linear , Therefore, proportionality constant represent slope of line.

Answer:

x = -7

y = 42

Step-by-step explanation:

y = -6x

y = -8x - 14

substitute -6x in the second equation for y

-6x = -8x - 14

add 8x to both sides

2x = -14

divide both sides by 2

x = -7

----------------

substitute that in to the first equation to solve for y:

y = -6(-7)

y = 42

----------------------------------

check the math:

y = -8x - 14

42 = -8(-7) - 14

42 = 56 - 14

42 = 42

Answer: B

Step-by-step explanation: Looking at the graph you can see B matches all the fields needed

Answer:

Step-by-step explanation:

5. 3x + 5 = 2x + 3

    x + 5 = 3

x = 2

y = 2(2) + 3 = 4 + 3 = 7

(2, 7)

6. 2x + y = 4

   3x - y = 1

    5x = 5

      x = 1

    2 + y = 4

     y = 2

 (1, 2)

7. 1/3x + 2 = 1/6x + 4

  2/6x + 2 = 1/6x + 4

   1/6x + 2 = 4

   1/6x = 2

   x = 12

y = 1/3(12) + 2= 4 + 2 = 6

   (12, 6)

Answer: 9 would be the width of the cornfield. the area if both L and W doubled would be 252

Step-by-step explanation:

all you gotta do is divide 63 by 7 and you will get the width, 9.

formula: A/L=W  

the area would be 252 if doubled both length and width because its multiplying 2 by 7 and 9, equaling to 14 and 18, which you multiply that together.
