C. The Y value does not change because you are only reflecting over x= lines. After the first, it is (-3.5). Then (7, 5)

Find the volume and surface area of the square pyramid

Montano1993 [528]

The volume and surface area of the pyramid will be 392 / 3 cubic units and 189 square units. Then the correct option is A.

The complete question is attached below.

<h3>What is the volume and surface area of the pyramid? </h3>

Suppose the base of the pyramid has length = L units, width = W units, slant height = K units, and the height of the pyramid is of H units.

Then the volume of the pyramid will be

V = (L × B × H) / 3

The surface area of the pyramid will be

SA = 2(1/2 × B × K) + 2(1/2 × L × K) + (L × B)

Then the volume will be

V = (7 × 7 × 8) / 3

V = 392/3 cubic units

Then the surface area will be

SA = 2(1/2 × 7 × 10) + 2(1/2 × 7 × 10) + (7 × 7)

SA = 189 square units

Then the correct option is A.

More about the volume and surface area of the pyramid link is given below.

Can the sides of a triangle have lengths 2, 10, and 11?<br> yes<br> no

madreJ [45]

Answer:

Yes

Step-by-step explanation:

Triangle inequality theorem states that a triangle can exist if

a + b > c; a + c > b; b + c > a

a = 2; b = 10; c = 11

2 + 10 = 12; 12 > 11.

2 + 11 = 13; 13 > 10.

10 + 11 = 21; 21 > 2.

x squared plus y squared equals 80. My daughter has to work out what x and y are. I have worked it out by trial and error, but k

olya-2409 [2.1K]

you Need to think of 2 square numbers that add up to make 80

answer:

64 + 16

this means that x = 8 and y = 4

because of the square roots

or

y = 4

and

x = 8
