Answered by Ti
Thank you so much for helping me Sara!!
It means a lot.
Answered by Sara
Equation: (x+3)^2+(y-2)^2=16
Answered by Ti
Thank you so much!!!
Answered by Sara
Omg wait the radius is 7 actually
Sooo sorry
Answered by Sara
Which means that the equation will actually equal 49
Answered by Sara
I found the radius by subtracting the x-values of the center and one of the endpoints
So (-3,2) is the center and (4,6) is an endpoint so 4- -3= 7
