Question

The centre of a circle is origin and its radius is 13 cm. a)Check whether the point( 12 ,5) is on the circle.b) write the co-ordinate of other three points on the circle​

Answer 1

Answer:

the equation of the circle-

x^2+y^2=13^2

or x^2+y^2=169

putting x=12 and y=5, the equation is satisfied,

hence (12,5) is a point on the circle.

The other three points are (5,12), (0,13), (-12,-5)
