Circumference = 2 pi r

11304 = 2 x 22/7 x r
11304 x 7/2x22 =r = 1798.36

If a right circular cone intersects a plane that runs parallel to the edge of the cone, the resulting curve will be a
gulaghasi [49]

If a right circular cone intersects a plane that runs parallel to the edge of the cone, the resulting curve will be a <u>parabola</u>.

A parabola is curved from one end and open from other end, therefore it would fit the best.

Hope I could help! :)

A.(2,1)
Alex17521 [72]

Answer:

  D(6, 3)

Step-by-step explanation:

The diagonals of a rectangle bisect each other, so the midpoint of AC is the same as the midpoint of BD. This means ...

  (A +C)/2 = (B +D)/2 . . . . the midpoints are the same

  A +C = B +D . . . . . . . . . multiply by 2

  D = A +C -B = (2+5-2, 1+5-3) . . . . . solve for D, substitute given coordinates

  D = (6, 3)

A 2x2 square is centered on the origin. It is dilated by a factor of 3. What are the coordinated of the vertices of the square?
Alexxx [7]

<u>Answer</u>:

The vertices are:

A' = (-3, -3)

B' = (3, -3)

C' = (3, 3)

D' = (-3, 3)

The ratio of area of  larger square to smaller square is 9:1

<u>Step-by-step explanation:</u>

Given:

A 2 x 2 square is centered at the origin.

So, the center of the square is (0, 0)

Since it is 2 x 2 square, the side of the square is 2 units.

So, the vertices of the 2 x 2 square are A (-1, -1),  B(1, -1), C(1. 1), D(-1, 1)

The above square is dilated by a factor of 3.

Let's name the dilated square A'B'C'D'

To find the coordinates of the vertices of dilated square, we need to multiply each vertices of ABCD by 3.

A(-1, -1) = 3(-1, -1) = A'(-3, -3)

B(1, -1) = 3(1, -1) = B'(3, -3)

C(1, 1) = 3(1, 1) = C'(3, 3)

D(-1, 1) = 3(-1, 1) = D'(-3, 3)

To find the area of the small square

the side  of the small square is 2 units

so the are of the small square is 2^2 = 4 square units

To find the area of the larger square

lets find the side AB of the square using distance formula

=>\sqrt{(x_2 -x_1)^2 +(y_2-y_1)^2}

=>\sqrt{(3 - (-3))^2 +(-3 - (-3))^2}

=>\sqrt{(3 +3)^2 +(-3 +3)^2}

=>\sqrt{(6)^2 +(0)^2}

=>\sqrt{36}

=>6

AB =6 units

In a square all the sides will be equal

Now the area of the larger square will be

6^2

36 square units

The ratio of larger square to smaller square is

=>36 : 4

=>9 : 1

How do I "undo" multiplication
Law Incorporation [45]
A way of undoing any operation, is using the inverse of the operation. So if you want to ‘undo’ addition you subtract, and if you want to ‘undo’ multiplication you divide.

Hope this helps!!

Use the formula d = rt to find the distance, rate, or time
Varvara68 [4.7K]

Answer:

16. d = distance

     r = rate

     t = time.

We know that the rate = 4, and time = 11.

=> d = 4 * 11

=> d = 44

17. We know that distance = 36, and time = 4.

=> 36 * r* 4

=> 36 = 4r

=> 36/4 = 4r/4

=> r = 9
