#C14841. Point in Sphere Determination
Point in Sphere Determination
Point in Sphere Determination
You are given a point in 3-dimensional space with coordinates \(x\), \(y\), \(z\) and a positive radius \(r\). Your task is to determine if the point lies inside or on a sphere centered at the origin. The mathematical criterion for this is:
\(x^2 + y^2 + z^2 \le r^2\)
If the condition holds, print True
, otherwise print False
.
inputFormat
The input is given from stdin as a single line containing four space-separated numbers: \(x\), \(y\), \(z\), and \(r\), where \(r\) is guaranteed to be a positive number.
outputFormat
Output to stdout a single line: True
if the point is inside or on the sphere, and False
otherwise.
