The equation of a circle with center (a,b) and radius r is:
(x - a)^2 + ( y -b)^2 = r^2
The center of the circle graphed is (3,4).
And the radius may be calculated using the distance formula and the points (0,0) and (3,4)
r^2 = (3 - 0)^2 + (4 - 0)^2 = 9 + 16 = 25
=> (x - 3)^2 + (y - 4)^2 = 25
Which is likely the option D, but you made a mistake when wrote the numbers.
Answer: (x - 3)^2 + (y - 4)^2 = 25
A and c are the correct answers
So copy the url of that into another tab and then go to the question, go back to the original guess all and final check it it will show the correct answer. Now take that answer and put it in the copy rang you made and vuala
Do they give you a graph?
