Use a net of the square pyramid, if necessary, to find the surface area of the pyramid.

Answers

Answer:

160

Step-by-step explanation:

You take the area of one of the triangles, which is 24, multiply that by 4. You get 96. You then add 64, the area of the square base, and end up with 160.

Answer:

160 units squared

Step-by-step explanation:

First we need to find the surface area of one of the triangles;

(8*6*0.5)

24

Next, we find the surface area of all of the triangles;

(24*4)

96

The next step is to find the surface area of the square;

(8*8)

64

The last step is to fins the surface area of the whole thing.

(96+64)

160

The surface area of the pyramid is going to be 160 units squared

Answers

Answer:

263.76

Step-by-step explanation:

It is 7 times 12 times 3.14. Then you round your answer

The formula for the volume of a cylinder is V=πr^2h. Which is volume equals pie * radius squared * height. pie = 3.14. radius is diameter/2, 3.5 in this case, then squared which is 3.5 * 3.5. And the height is 12. You take 3.14, 3.5^2, and 12 then multiply each term. So your substituted equation would be V=3.14(3.5^2)12.

This is how it would go:

V=3.14(3.5^2)12.
3.5^2 = 12.25.
- just squared 3.5, that equals 12.25

V=3.14(12.25)12
3.14 * 12.25 = 38.465
- pie times 12.25 equals 38.465

V=38.465(12)
38.465 * 12 = 461.58
- 38.465 * 12 = 461.58

V=461.58
- Your answer is 461.58 centimeters!!

The city mayor wants to use the reserved section of a rectangular park for gardening lessons conducted by the city public school. The rest of the park will be turned into a lawn. What will the area of the lawn be?

A. 168 square feet
B. 224 square feet
C. 280 square feet
D. 448 square feet

Answers

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.

C . 280 square root

The answer to this is 100

Answer:

its 100

Step-by-step explanation:

well since its a parallel line, 7 and 3 are corresponding and that makes 3 also 80. buh then 3 is also adjacent to 2 and that makes it also 80 and since 2 is on the same line as 1 and an angle on a straight line is 180, it automatically makes 1 an angle of 100 as 180 - 80 should give u 100.

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

The surface area of the hexagonal pyramid is,

⇒ Surface Area of Hexagonal Pyramid = 478.32 square units

What is an expression?

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
