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
Answers
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
Final answer:
The original circle's radius cannot be definitively determined from the question as is, because the dilated circle's radius is not specified. However, if the dilated circle's radius is known, the original radius can be found by dividing the dilated radius by the scale factor, which is 2 in this case.
Explanation:
The question represents a geometric concept in Mathematics, specifically dealing with dilation of a circle. In dilation, a figure is altered in size without changing its shape. If a circle is dilated by a scale factor of 2, meaning it has been made twice as large, the radius of the dilated circle will be two times the radius of the original circle. If the scale factor is 2, the radius's length will be halved to get the measurement of the original circle's radius. Therefore, without the specific measurement of the dilated circle's radius, we can't definitively give the original circle's radius from the options given (A. 2 units, B. 2.75 units, C. 5.5 units, D. 11 units).
