3 is the scale factor you would use to dilate Figure A to Figure B.
6.75pi is the answer because radius is half of diameter and 1.5^2 • 3 is 6.75
Answer:15
Step-by-step explanation:

In the given figure, the Angle (6v - 4)° forms vertical opposite angle pair with 50° , so their measures is equal to one another.
that is :
therefore, value of v = 9°
Well 36x4=144
So you have do this equation
36x4=144√=12
So the square root of 144 or 36x4 is 12
