Answer:
r = 11 units
Step-by-step explanation:
Given that,
The measure of Arc CD is 11x
The arc is making an angle of 180°.
We know that,
Length of the arc, ![l=r\theta](https://tex.z-dn.net/?f=l%3Dr%5Ctheta)
Where
r is the radius of the circle
So,
![r=\dfrac{l}{\theta}\\\\r=\dfrac{ 11\pi}{\pi}\\\\r=11](https://tex.z-dn.net/?f=r%3D%5Cdfrac%7Bl%7D%7B%5Ctheta%7D%5C%5C%5C%5Cr%3D%5Cdfrac%7B%2011%5Cpi%7D%7B%5Cpi%7D%5C%5C%5C%5Cr%3D11)
So, the radius of the circle is equal to 11 units.

Answer:
(x + 3, y - 2)
Step-by-step explanation:
we know that
The rule of the transformation T is equal to
T: pre-image → image
T: (x, y) → (x',y')
T: (x, y) → (x - 3, y + 2)
so
x'=x-3 ----> x=x'+3
y'=y+2 ----> y=y'-2
The rule of the inverse of transformation T -1 is equal to
T-1: image → pre-image
T-1: (x', y') → (x,y)
T-1: (x', y') → (x'+3, y'-2)
