If a rectangle is rotated about the y-axis as shown below, what three-dimensional figure would be formed?

Xelga [282]

Answer:

Cylinder. The explanation is not very exact, more intuition and whatnot, so let me know if there was anything you did not understand.

Step-by-step explanation:

This is assuming the rectangle has its sides parallel with the x and y axes.

Let's try to eliminate them one by one. A cone does not seem likely since it has slanted sides, and spinning the two straight sides will keep the sides straight. This can be used for the pyramid as well. Let me know if this doesn't make sense though.

Now for me I would imagine that rectangle being a sheet of paper, or metal. if you set that sheet atop some dirt or something and then rotated it, what shape would be drawn into the material? It would be a circle. So we know the 3d shapewill have a base of a circle, which leaves us with a cylinder. Again, let me know if this method did not make sense.

Drag expressions into order to show a way to find 3 × 56.

lina2011 [118]

As we could "drag" these together, we could then do it the easy way.

56
+56
+56
-------
168
------------------------

Or we could also do the following:

56 $*$ 3:

6 $*$ 3= 18.

Carry the one.

5 $*$ 3 = 15+1 (which was carried). = 16

(16+8) = 168

An advertising company is designing a new logo that consists of a shaded triangle inside a parallelogram.What is the area, in sq

tatyana61 [14]

<h2>Explanation:</h2><h2 />

The complete question is shown in the figure below. As you can see one square units is well shown in the graph. So we can conclude that the distance between two consecutive points is 1 unit. If so, then we can calculate the area of the parallelogram as follows:

$A=b\times h \\ \\ A:Area \\ \\ b:Base \\ \\ h:Height \\ \\ \\ CB=b \\ \\ AB=h$
