Answer:
See below
Step-by-step explanation:
I'm not sure if there are any specific instructions on how these answers are supposed to be written, but here's my best shot:
1. U
2. XZ, VY
3. VU, WU
4. XY, ZY
5. ⊙U
6. XZ, VY (they are diameters but also intersect)
7. VY = 10 cm, WU = 5 cm
8. Diameter (of larger circle)
9. Diameter (of smaller circle)
10. Radius (of larger circle)
11. Radius (of smaller circle)

Answer: (x - 2)^2 + (y + 3)^2 = 34
Step-by-step explanation:
The basic equation for a circle is
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre of the circle
Using Pythagoras we can find r^2
r^2 = (2 - -1)^2 + (-3 - -8)^2
= 3^2 + 5^2
= 34
So the circle is (x - 2)^2 + (y - -3)^2 = 34
