A circle is centered at H (4,0) and has a radius of 10. Where does the point L(-2,8) lie? (khan)
a. inside the circle
b. on the circle
c. outside the circle

b) on the circle

The point lies on the circle S =0

Step-by-step explanation:

Step(i):-

Given center of the circle = H(4,0)

Radius of the circle 'r' = 10

Equation of the circle

Step(ii):-

S =0 is a circle and P(x₁ , y₁) be a point in its plane

Then (i) P lies inside the circle S = 0 ⇔ S₁₁ < 0

         ii) P lies outside the circle S = 0 ⇔ S₁₁ > 0

        iii) P lies on the circle S = 0 ⇔ S₁₁ = 0

now

Given point ( -2 , 8)

P lies on the circle S = 0 ⇔ S₁₁ = 0
