Radius after dilation = 4 * 1/2 = 2 in

Now, C = 2πr
C = 2π(2)
C = 4π
Or C = 4 * 3.14 = 12.56

In short, Your Answer would be 4π or 12.56 in

Hope this helps!

Answer:

The circumference after dilation is 12.56 in.

Step-by-step explanation:

Given : A circle with a radius of 4 in. is dilated by a scale factor of 1/2.

To find : What will be the circumference of the circle after dilation?

Solution :

Radius is 4 in.

Radius is dilated by scale factor \frac{1}{2}

Radius after dilation = 4 \times\frac{1}{2}= 2

Circumference of circle is C=2\pi r

Put radius = 2 in. and \pi =3.14

C=2\pi r

C=2\times 3.14\times2

C= 12.56

Therefore, The circumference after dilation is 12.56 in.

Answer:

(n+2)^2+6

Step-by-step explanation:

Pattern 1 consists of

3+3\times 3+3 small squares (here n = 1 and 3\times 3=(1+2)\times (1+2)).

Pattern 2 consists of

3+4\times 4+3 small squares (here n = 2 and 4\times 4=(2+2)\times (2+2)).

Pattern 3 consists of

3+5\times 5+3 small squares (here n = 3 and 5\times 5=(3+2)\times (3+2)).

Thus, pattern n consists of

3+(n+2)\times (n+2)+3=6+(n+2)^2 small squares.

andrew11 [14]

Answer:

Question 1: Answer would be A.

Question 2: Answer would be B.

Question 3: I cannot answer this one because an image is not provided. I do not have the image of the original triangle LMN. If you message me with a photo of this question, I will be able to answer.

Question 4: This answer may be wrong, but I believe that it would be A. I don't know how to calculate dilation transformations, but after graphing out all the points, I found that (6,4) would be the correct point because the distance between Point S and (6,4) is even and is able to be divided by two.

Question 5: Again, I cannot answer this one because an image is provided. Message me with a photo, I'll answer.

Question 6: Answer would be C.

Question 7: Again, I cannot answer this one because an image is provided. Message me with a photo, I'll answer.

Question 8: Answer would be C.

Step-by-step explanation:

Question 1 Explanation: Answer would be A because the quadrilateral was rotated 180 degrees and dilated to be larger.

Question 2 Explanation: Quadrant IV is on the bottom right, Quadrant I is on the top right. If a triangle were to be rotated from the origin (0,0), it would have to rotate 270 degrees in order to reach Quadrant I.

Question 3 Explanation:

Question 4 Explanation:

Question 5 Explanation:

Question 6 Explanation: Using a rotation calculator, I input the degree of rotation as -90.

Question 7 Explanation:

Question 8 Explanation: Using a rotation calculator, I input the degree of rotation as -180.
