Answer:

[tex] a=1.58, \: \: a =-7.58[/tex]

Step-by-step explanation:

Since, circle of center (-3 , -2) is passing through the points (0 , -6) and (a , 0).

Therefore, points (0 , -6) and (a , 0) will be equidistant from the center of the circle (-3 , -2).

Hence,

Distance between (0 , -6) and (-3 , -2) = Distance between (a , 0) and (-3 , -2).

[tex] [0-(-3)]^2 + [-6-(-2)]^2=[a-(-3)]^2 + [0-(-2)]^2[/tex]

[tex] [0+3]^2 + [-6+2]^2=[a+3]^2 + [0+2]^2[/tex]

[tex] [3]^2 + [-4]^2=[a+3]^2 + [2]^2[/tex]

[tex] 9 + 16=[a+3]^2 + 4[/tex]

[tex] 25=[a+3]^2 + 4[/tex]

[tex] 25-4=[a+3]^2[/tex]

[tex] 21=[a+3]^2[/tex]

[tex] [a+3]^2=21[/tex]

[tex] [a+3]=\pm\sqrt {21} [/tex]

[tex] a=\pm\sqrt {21} - 3[/tex]

[tex] a=\sqrt {21} - 3, \: \: a =-\sqrt {21} - 3[/tex]

[tex] a=1.58257569, \: \: a =-7.58257569[/tex]

Answer:

the answer is C (280 square feet)

Step-by-step explanation:

First, cut the lawn so that it becomes two shapes: a rectangle, and a triangle. Solve for both areas.

A(r) = lw

A(r) = (14)(16)

A(r) = 224 square feet

A(t) = bh/2

A(t) = (8)(14) / 2

A(t) = 112 / 2

A(t) = 56 square feet

Add the two areas:

A(r) + A(t) = Area of lawn

224 square feet + 56 square feet = 280 square feet.

Answer:

Diameter: 14

Radius: 7

Step-by-step explanation:

To find the diameter, you do 43.96 divided by 3.14 and that equals 14

To find the radius, you just divide 14 by 2 and that equals 7.

Answer:

Basically for this problem, we want to order these five numbers from greatest to least.

So, we should have: 12.8, 12.08, 11.301, 11.283, 11.09.

This would make C the correct answer.

Answer:

She can buy 8 bags of soil

Step-by-step explanation:

2.7s + 14.9 < 39.2

Subtract 14.9 from both sides

2.7s  < 39.2 - 14.9

2.7s < 24.3

Divide both sides by 2.7

s < 24.3 /2.7

s < 8.89

The Surface area of hexagonal pyramid= 358.32 cm square

Formula of surface area of hexagonal pyramid= 3ab+3bs
where a = apothem of pyramid
            b= base
            s= slant height
here a= 6.93cm
         b= 8cm
         s= 8cm*
* a^2 + b/2 ^2 = s^2
  6.93^2 + 4^2 = 8
Area = 3*6.93*8+ 3*8*8= 358.32

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

In the diagram of the base of the hexagonal pyramid, all the triangles are the same.

Here, The slant height of the pyramid (s) = 13 cm

And, Base (b) = 8 cm

And, Apothem (a) = 6.93 cm

Now, We know that;

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = (3ab + 3bs) square units

After putting the values we get;

⇒ Surface Area of Hexagonal Pyramid = (3 × 6.93 × 8 + 3 × 8 × 13) square units

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

Thus, The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units
