Find the volume of the cylinder. Use 3.14 for Pi
9 cm height
6.5cm

A.1,194.6
B. 298.5
C. 633
D. 367.4

Answer:

77

Step-by-step explanation:

I'm pretty sure this is the answer because the complement of a 13 degree angle is 13 plus a number is equal to 90. So, that number is 77 because 77 plus thirteen is 90. plz mark me brainliest!

The angle which is complementary to the 13 degrees is equal to 77 degrees.

Use the concept of the complementary angle defined as:

Complementary angles are those whose combined angle is 90 degrees or less.

To put it another way, two angles are said to be complimentary if they combine to make a right angle. In this case, we say that the two angles work well together.

The given angle = 13 degree

Now let the other angle complement this = A degree

Therefore,

A + 13 = 90

Subtract 13 on both sides,

A = 77 degree,

Hence,

The required complement angle is 77 degrees.

Area = 7.853981 in^2                (2.5 Pi)

Perimeter = 11.42478 in              (3.63Pi)

Step-by-step explanation:

Area

Lg semi circle area = Pi(2^2)(0.5) = 3.141593(4)0.5) = 6.283185 in^2

Sm semi circle area = Pi(1^2)(0.5) = 3.141593(2)(0.5) = 1.570796 in^2

added together = 7.853981 in^2

Perimeter

Lg semi circle perimeter = Pi(4)(0.5) + 2 = 8.283185 in

Sm semi circle perimeter = Pi(2)(0.5) = 3.141593 in

added together = 11.42478 in

Answer:

2372

Step-by-step explanation:

You would do the equation 2332-372+412

Answer:

Here' a quick summary of the answers:

Question a: center =  (3, 2), scale = 9 / 20

Question b: center = (8, -1), scale = 3

Question c: center = (6, 4), scale = 3 / 2

Question d: center = (5, 3), scale = 2

Step-by-step explanation:

By "find the center of dilation", they're asking you to name the x/y point at which the image is scaled from.

The scale factor is the amount that the points are being scaled by to reach the "prime" of  them (noted by the apostrophe).  e.g., A would be the original point, and A' would be the transformed one.

To answer these, we'll need to pay careful attention to the coordinates in the graph.  To get the scale, you can simply look at the equivalent side on both triangles, and compare the lengths.

In question A for example, we can see the line AC is 10 units wide, and the equivalent line A'C' is 4.5 units wide.  This tells us that the triangle was scaled down by a factor of 4.5/10, or 9/20, or 45%

Finding out the center of dilation can be slightly more complicated. Note that there may be an easier way to do this that I am personally unaware of, but one way to do it would be to take the original and transformed versions of two points, e.g.  A and A', and B and B', and use those points to define lines.  We can then find where those lines intersect, and that tells us where the point of origin is.

Question A:

For example, in question A, the points A and A' are at (7, 4) and (5, 3) respectively.  Remember that the slope of a line is equal to rise over run.  In other words

s = (Ay - A'y) / (Ax - A'x)

s = (4 - 3) / (7 - 5)

s = 1/2, or 0.5

Now we can take that slope, and either of the the two points we used, and apply it to a point to define a line, using the formula Δy = sΔx

y - Ay = s(x - Ax)

y - 4 = 0.5(x - 7)

y = 0.5x - 3.5 + 4

y = 0.5x + 0.5

That gives us the line along which point A was translated when the triangle was scaled.  Now let's find the same for point B:

s = (By - B'y) / (Bx - B'x)

s = (1 - 0) / (4 - 5)

s = 1 / -1

s = -1

And apply that slope to build our line:

y - By = s(x - Bx)

y - 0 = -1(x - 5)

y = -x + 5

Now that we have two lines created, we can simply equate them, solving for x, which tells us the x location of the center of dilation.

Given:

y = -x + 5

and

y = 0.5x + 0.5

we can say:

-x + 5 = 0.5x + 0.5

-2x + 10 = x + 1

-3x = -9

x = 3

So the center of dilation has an x coordinate of 3.  To find it's y coordinate, we merely need to plug that into one of the line equations we already worked out:

y = -x + 5

y = -3 + 5

y = 2

So for question A the center of dilation is at (3, 2)

Question B:

This one is actually much easier, as we don't need to work out line equations to find the point of origin.  The thing to notice here is that A and A' have the same x coordinate, forming a vertical line.  Also B and B' have the same y coordinate, forming a horizontal line.  All we need then is to know where those lines intersect.  We can get that by taking the x coordinate of A and the y coordinate of B.

A lies at (8, 0), and B lies at (5, -1), so the center of dilation is (8, -1)

Using the same logic as above to find the scale, we get a scale of 3.  This is easiest by comparing |CA| with |C'A'|, the left sides of the triangles.  As you can see, that side is scaled up by a factor of 3.

Question C:

This one is far easier, as it is very obvious from the image that point A, at (6, 4) is the point of dilation.  Using the same technique as above we can see that the scale is  3/2, or 1.5

Question D:

Again much easier, as we can see that the point of origin is on the halfway point of the side CA, (5, 3).  Using the same method as above, we can see that the scale is 2.

Step-by-step explanation:

First what I did was find how much each pound would cost per different package.

So starting off with the 3 pound package. I did 2.49 divided by 3 to find out how much each pound would weigh.

2.49 / 3 = 0 . 83

So each pound in the 3 pounded package would cost $0.83.

Now to see how much the 8 pound package would cost. Just like the 3 pound package I had to find how much each pound would weigh. So I divided 6.49 by 8.

6.49 / 8 = 0.81125

So looking at the results the 3 pound package would be the best option. You are getting more for less.

Radius of larger circle (2t): 2 * 4 = 8

Step-by-step explanation:

π * (2t)² + π * (t)² = 80π

4 πt² + π t² = 5 πt² = 80π

t² = 80π / 5π = 16

t = 4

Radius of larger circle (2t): 2 * 4 = 8

Answer: 34

Step-by-step explanation: the ratio is 3:2 we know that there are 51 orange sweets but we don’t know how many are yellow so the current ratio is 51:x we need to find x so if we divide 3 by 51 the answer is 17 so we need to multiply 17 by 2 which is 34 so x is equaled to 34 the final ratio is 51:34

Answer:

True.

Step-by-step explanation:

A rhombus has four side of the same length (sometimes) and bisecting diagonals.

A square has what a rhombus has, as well as what a rectangle has.

A rectangle has parallel sides, four right angles, and congruent diagonals.

That means that a square has four right angles, four sides of the same length, and bisecting diagonals.

That's why a square is a rhombus and a rectangle but not its converse.

So, true.

Every rhombus with four right angles is a square. Therefore, the given statement is true.

A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square. Look at the image below to understand the relationship of rhombus shape with parallelogram and square.

A square is a quadrilateral with four equal sides. There are many objects around us that are in the shape of a square. Each square shape is identified by its equal sides and its interior angles that are equal to 90°.

Therefore, the given statement is true.
