To do this, use this formula=The area is always pie times the radius to the 2nd(\pi r^{2} ). The radius is half the diameter(22/2) which is 11. Now we need to bring this to the power of 2 (11x11), which is 121. Now we multiply by pie (3.14x121) which is 379.94. Your answer is

<h2>379.94 inches!!!!</h2>

The formula for the area of a circle is A = π r^2


r is the radius, which is half of the diameter.


The diameter is given as 22 inches, the radius would be 2 /2 = 11 inches.


Area = 3.14 * 11^2

Area = 3.14 * 121

Area = 379.94 square inches.

Help me pls math genius

Answer:

x = -3

y = -1

Step-by-step explanation:

in the given question :-

=》x - 4y = 1

=》x = 4y + 1

now replacing the value of x as ( 4y + 1 ) in equation (2)

=》3x + 2y = -11

=》3 (4y + 1) + 2y = -11

=》12y + 3 + 2y = -11

=》14y = -11 - 3

=》y = -14 ÷ 14

=》y = -1

now, putting the value of y in equation (1)

=》x - 4y = 1

=》x - ( 4 × -1 ) = 1

=》x + 4 = 1

=》x = 1 - 4

=》x = -3

Abdul is working on a project and has cut a number of wooden blocks of equal size that are represented by this right rectangular
Valentin [98]

The amount of fabric needed to cover 8 blocks is 192cm.

<h3>How much fabric is needed to cover 8 blocks?</h3>

In order to determine the amount of fabric needed, the total surface area of the rectangular prism has to be determined. The total surface area of the rectangular prism is the sum of the areas its faces.

Total surface area of a rectangular prism = 2 (lw + wh + lh)

where:

  • l = length
  • w = width
  • h = height

2 x [(4 x 1/2) + (1/2 x 2) + (4 x2)] = 24cm

Fabric needed fo 8 blocks = 24 x 8 = 192cm

Let's solve :

a.) The equation will be :

  • xy =  - 3

  • y =  \dfrac{ - 3}{x}

b.) the table will be like this :

  • for x = 1 , y = -3

point (1 , -3)

  • for x = 3 , y = -1

point (3, -1)

  • for x = -1 , y = 3

point (-1 , 3)

  • for x = -3 , y = 1

point (-3 , 1)

c.) graph the equation as shown in attachment !

5^15= 30517578125 people

Step-by-step explanation:

x=# of cycles= 15 cycles

y= #of people recruited = what we're figuring out

Plug in 15 for x in the equation y=5^x

y= 5^15= 30517578125 people
