<h3>
Answer: B) 15 degrees</h3>
==========================================
Explanation:
The radius of the circle is 24, so the circumference is
C = 2*pi*r
C = 2*pi*24
C = 48pi
The whole distance around the circle (perimeter) is exactly 48pi units
However, we only want 2pi of those units as the arc length shows
Divide 2pi over 48pi, and reduce
(2pi)/(48pi) = 1/24
So the arc shown is 1/24th of a full 360 degree revolution. Meaning we multiply the fraction 1/24 by 360 to get
(1/24)*360 = 360/24 = 15
The arc measure is 15 degrees which is equal to the measure of the central angle as well.

C loser that’s the correct number
Scale factor is simply the ratio of sides of two corresponding figures
<em>The estimated scale factor is 1.5</em>
From the question, we have:
- The actual figure is AB
- The dilation is AC
- The center of dilation is A
So, the scale factor (S) would be:
![\mathbf{S = \frac{AC}{AB}}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%20%5Cfrac%7BAC%7D%7BAB%7D%7D)
The actual measurements are not given; so, we will make use of estimates
The estimates to use are:
![\mathbf{AB = 1}](https://tex.z-dn.net/?f=%5Cmathbf%7BAB%20%3D%201%7D)
![\mathbf{AC = 1.5}](https://tex.z-dn.net/?f=%5Cmathbf%7BAC%20%3D%201.5%7D)
So, the scale factor is:
![\mathbf{S = \frac{1.5}{1}}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%20%5Cfrac%7B1.5%7D%7B1%7D%7D)
![\mathbf{S = 1.5}](https://tex.z-dn.net/?f=%5Cmathbf%7BS%20%3D%201.5%7D)
Hence, the estimated scale factor is 1.5
