Answer:
![r =5](https://tex.z-dn.net/?f=r%20%3D5)
Step-by-step explanation:
Given
-- center
--- pass through
Required
The radius (r)
The equation of circle is:
![(x - h)^2 + (y - k)^2 = r^2](https://tex.z-dn.net/?f=%28x%20-%20h%29%5E2%20%2B%20%28y%20-%20k%29%5E2%20%3D%20r%5E2)
So, we have:
![(1 - -3)^2 + (5 - 2)^2 = r^2](https://tex.z-dn.net/?f=%281%20-%20-3%29%5E2%20%2B%20%285%20-%202%29%5E2%20%3D%20r%5E2)
![(4)^2 + (3)^2 = r^2](https://tex.z-dn.net/?f=%284%29%5E2%20%2B%20%283%29%5E2%20%3D%20r%5E2)
![16+9 = r^2](https://tex.z-dn.net/?f=16%2B9%20%3D%20r%5E2)
![25 = r^2](https://tex.z-dn.net/?f=25%20%3D%20r%5E2)
Take square roots of both sides
![5 = r](https://tex.z-dn.net/?f=5%20%3D%20r)
![r =5](https://tex.z-dn.net/?f=r%20%3D5)
Answer:
1/3 ≅ .33333
Step-by-step explanation:
If 'i' is 1, then 5+i is 6. 2 over 6 is 1 over 3. (2/6 = 1/3) 1 over 3 is also .3333... forever repeating.
