Which of the following is an equation of the circle with its center at (0,0) that passes through (3,4) in the standard (x,y) coordinate plane?
A. x – y = 1
B. x – y = 25
C. x2 + y = 25
D. x2 + y2 = 5
E. x2 + y2 = 25
E. x2 + y2 = 25
Solution:
circle equation: (x1-x)2+(y1-y)2=r2
r=radius, (x1, y1)=center of circle=(0,0)
r=distance from center to point - use distance formula with (0,0) and (3,4)
r=squareroot((3-0)2+(4-0)2) r=5
x2 + y2 = 25
