The figure above represents a circle that has been dilated by a scale factor of 2.
what is the measurement of the radius of the original circle?
answer choices are below
a. 2 units
b. 2.75 units
c. 5.5 units
d. 11 units

If you look at the graph closely it has the y axis (top circle limit) on 5 and bottom -6
Same on the x axis to the left -5 to the right circle 6
total amount from onside to another is 11 which make the diameter 11.
Radius? divide the diameter which is 11/2 = 5.5
it says it has been dilated. If it has been re-sized smaller then it B. 2.75
5.5 divided by 2 = 2.75

Dcups i think
