Answer:
The correct option is 3. The value of x is 8 inches.
Step-by-step explanation:
It is given that Figure A is dilated by a scale factor of 1/2 to form Figure B. It means both figure are similar and corresponding sides of similar figures are proportional.


Multiply both sides by 16.


Since scale factor is 1/2, so we can directly say that the side length of image is half of the corresponding side of preimage.
The length of x is 8 inches. Therefore the correct option is 3.
Answer:
The answer is -4.
Step-by-step explanation:
Because the 4 x 4 is 16
Just work with it as seperate triangles and then add them up.
You would have to divide by 3.14 to find the radius squared, and to find the diameter, just add the radius plus the radius.
