Question

The circle below is centered at the point (4,3) and has a radius length 5. What is its equation

Answer 1

well, equation of circle is (X-X1)^2 + (Y-Y1)^2 = R^2

so, (X-4)^2 + (Y-3)^2 = 25

X^2 + 16 -8X + Y^2 + 9 - 6Y = 25

X^2 + Y^2  - 8X - 6Y = 0

this is the correct answer hope it helped :)
