Question

 If the point (x,4) lies on a circle whose centre is lying on the origin and radius is 5,then x=


a, +5 ,-5

b. +3 -3

c.0

d. +4-4

​

Answer 1

c=0

Answer:

answer is c beacuse it was nearly to 0

Answer 2

Answer:

x = 3,-3

Step-by-step explanation:

given that p(x,4) lies on circle

center of the circle is (0,0)

radius = 5

equation of the circle is. x^2 +y^2 =25

point p(x,4) lies on circle

;

x^2 + 4^2 =25

x^2 =25-16

x^2 =9

x= ±3
