Question

The circles below is centered at the point (4,3) and has a radius of length 8. Whats its equation?

Answer 1

$centered =(x_{o},y_{o})= (4,3) \\ radius : \ r= 8 \\ \\ General \ equation \ for \ circle: \\ \\ (x- x_{o} )^2+(y- y_{o} )^2 = r^2 \\ \\(x- 4 )^2+(y- 3 )^2 = 8^2 \\ \\(x- 4 )^2+(y- 3 )^2 = 64$
