WebFeb 2, 2024 · The equation of a sphere in the standard form is given by: \scriptsize \quad (x-h)^2 + (y-k)^2 + (z-l)^2 = r^2 (x − h)2 + (y − k)2 + (z − l)2 = r2 where: (x,y,z) (x,y,z) – Coordinates of any point lying on the surface of … Web5 years ago. You just need to use the equation. First, find the equation for the circle. Like this, x^2 + (y - 3)^2 = 9. Then, input the x and y values into the equation. If it's bigger than 9, the point is outside of the circle, if it's equal to 9, the point is on the circle, and if it's smaller than 9, the point is inside of the circle.
