Question

If P(4, -3) is a point
that lies on the
circumference of a
circle on a cartesian
plane with origin 'O’
as its centre, which
of the following
points would lie on
the circumference?​

Answer 1

Distance between (4,-3) &(0,0) = radius of the circle= √(4²+3²)=√25=5

the equation of the circle is,

x² + y² = 25

any point which will satisfy the above equation will be on the circle

like, (-4,-3) , (-4,3) , (4,3) lie on the circle.
