# If the Points(X, 4) Lies on a Circle Whose Centre is at the Origin and Radius is 5, Then X = - Mathematics

MCQ

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

•  ±5

•  ±3

• 0

•  ±4

#### Solution

It is given that the point A(x, 4) is at a distance of 5 units from origin O.

So, apply the distance formula to get,

5^2 = (x)^2 + 4^2

Therefore,

x^2 = 9

So,

x = +- 3

Is there an error in this question or solution?
