FALSE ANSWERS/SCAMS/TROLLS WILL IMMIDIATELY BE REPORTED!

Answers

Answer:

256 sq cm

Step-by-step explanation:

cube is a three-dimensional figure with six congruent square faces. Since each face is congruent, each of the edges have the same length.

The cross-section described is shown below.

The cross-section is also a square which is congruent to the other faces of the cubes. Therefore, the edges of the cross-section will each measure 16 cm. Find the area by using the formula for the area.

         A=lw

             =(16cm) (16cm)

                =256 sq cm  

So, the area of the cross-section is 256 sq cm.

hope this helps some way

Step-by-step explanation:

I need extras charters to submit dw abt this

Answer:

9/12, 2/6, 1/2

Step-by-step explanation:

First start with the original fractions given and figure out how 4 got to 12

3/4=x/12 so divide 12/4 = 3 so they multiplied 4 by 3 to get to 12 so just do that to the top as well.

3 x 3 = 9

3/4 = 9/12

For the second one you do the same thing

2/1 = 2

3 x 2 = 6

1/3 = 2/6

For this last one just choose any number you want to multiply since its open ended.

2/4

Im just going to simplify it. Which means you do the reverse of the other two instead of multiplying youd divide the 2 numbers by a common factor which would be 2 in this case.

2/4 = 1/2

The figure consists of two quarter circles and a square.


What is the perimeter of this figure?


Use 3.14 for π.


82.24 in.


114.24 in.


132.48 in.


164.48 in.

Answers

Answer:

B, 114.24

Step-by-step explanation:

The sides of the square = 32 in. Add the flat sides of the quarter circles = another 32 in. = 64in of flat sides

The circumference of the circle, if it was whole, is (2)(pi)(r) = (2)(3.14)(16) = 100.48. We have 2 quarter circles, so we'll cut that answer in half for those arcs. = 50.24in of curved sides.

64 + 50.24 = 114.24, answer B of your choices.

114.24 hope it helps
