Question

Which of the following circle equations represents a circle whose center is at (0, 0)?

Answer 1

x2 + y2 = 45



(x − 3)2 + (y − 5)2 = 0



(x + 3)2 + (y − 3)2 = 0



x2 + (y − 1)2 = 1

Answer 2

we can eassily say that first eqution... that is x2 + y2 = 45

Answer 3

becouse circle eqution is
(x - a)^2 + (y - b)^2 = 0

hear (a,b) are the center point..... compare the eqution with the give you will get the answer....
