Answer:

  256,096 ft²

Step-by-step explanation:

<u>Pyramid Area</u>

Each of the four faces is a triangle with a base of 756 feet and a height of 612 feet. The area of that triangle is ...

  A = 1/2bh

  A = 1/2(756 ft)(612 ft) = 231,336 ft²

The total area of the four visible faces of the Great Pyramid is ...

  pyramid area = 4 × 231,336 ft² = 925,344 ft²

__

<u>WTC Area</u>

Each of the four rectangular side faces of the WTC tower has a base length of 208 ft and a height of 1368 ft. The area of it is ...

  A = LW = (208 ft)(1368 ft) = 284,544 ft²

The area of the square top of the tower has an area that is ...

  A = s² = (208 ft)² = 43,264 ft²

The total area of the four visible sides and the top is ...

  WTC tower area = 4 × 284,544 ft² +43,264 ft² = 1,181,440 ft²

__

The difference between the areas is ...

  WTC tower area - Great Pyramid area =

     1,181,440 ft² -925,344 ft² = 256,096 ft²

The difference in visible area is 256,096 ft².

How to solve the problem 3.2d-4d=2.3d+3
Liula [17]
3.2d - 4d = 2.3d + 3...simplify by combining like terms
-0.8d = 2.3d + 3....subtract 2.3d from both sides
-0.8d - 2.3d = 3 ...simplify again
-3.1d = 3...divide both sides by -3.1
d = 3/ -3.1
d = - 0.97

or
3.2d - 4d = 2.3d + 3....multiply the equation by 10, gets rid of the decimals
32d - 40d = 23d + 30....subtract 23d from both sides
32d - 40d - 23d = 30....simplify
-31d = 30...divide by -31
d = -30/31
d = - 0.97

1. In the given figure O is the centre and PQ is the diameter of the circle. if the chord PR is produced to S and QR is joined t
Ksenya-84 [330]

Answer:

90°

Step-by-step explanation:

since PQ is the diameter of the circle, m <em>L</em><em> </em>PRQ = ½ × 180° = 90°.

so, as a supplementary to <em>L</em><em> </em>PRQ, the value of angle QRS = 180 - m <em>L</em><em> </em>PRQ = 180-90 =90°

What is the circumference of area=64pi mi^2
azamat

Answer:

  16pi mi

Step-by-step explanation:

The smallest circumference for a given area is that of a circle with that area. The area is given by ...

  A = πr²

so we can find r as ...

  64π = πr²

  r = √64 = 8 . . . . miles

The circumference of this circle is ...

  C = 2πr = 2π·(8 mi) = 16π mi

The circumference of the area is at least 16π miles.

_____

If the shape is not constrained to a circle, the circumference can be anything you like.

Which of the following is not true?
vovikov84 [41]

Answer:

B: m∠1 + m∠3 = m∠2

Step-by-step explanation:

The sum of a triangle is 180° so all of the angles in the triangle are equal to 180°. It is not possible for 2 of the angles in a triangle to be equal to the other angle in the triangle.

Hope This Helps :)
