Question

A circle is shown on the graph below. What is the equation of the circle?


Select one:
A. (x − 5)2 + (y − 5)2 = 25
B. x2 + y2 = 25
C. x2 − y2 = 25
D. (x + 5)2 + (y + 5)2 = 25

Answer 1

what do you think :D

Answer 2

B

Answer 3

i think that its B

Answer 4

since that is the equation to make a circle

Answer 5

ur correct :)

Answer 6

now can someone please help me :( and i could try and help you in a few

Answer 7

By assuming each interval is 1 unit we can find the radius easily to be r^2 or 25 units squared. and if you remember (h,k) is the center then you will have 0,0 units at the center leaving you with only x and y in the equation of a circle.
\[(x-0)^2+(y-0)^2 = 25\]
or \[x^2+y^2 = 25\]
