write an equation of each circle described:

2. Shiv99 Group Title

simply get the radius using distance formula and then u have centre and radius u'll get eqn of circle

3. Mrfootballman97 Group Title

So the radius is $\sqrt{10}$

4. SweetsAndEverything Group Title

@Mrfootballman97 Use this formula: $(x-a)^{2} + (y-b)^{2} = r ^{2}$

5. goformit100 Group Title

(x−a)2+(y−b)2=r2

6. Shiv99 Group Title

no duh it $\sqrt{26}$

7. Mrfootballman97 Group Title

so the final answer is? Im a little confused right now. If someone just tells me the answer ill be able to see how you did it.

8. Shiv99 Group Title

hey that not to find radius use$\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2}$

9. Shiv99 Group Title

@Mrfootballman97 use above formula to get radius and then equation of circle answer would be $x^2+(y-4)^2=26$

thank you!
