What is the distance between point (-3 4 -12) and the origin?
बिंदु (-3 4 -12) और origin के बीच दूरी कितनी है?
Show answer and explanation
Correct Answer
C. 13 / 13
ExplanationStep 1: Distance from origin is √(x²+y²+z²). Step 2: √(9+16+144)=√169=13. Step 3: In origin distance signs become positive after squaring.
Step 1: Origin से distance √(x²+y²+z²) होता है। Step 2: √(9+16+144)=√169=13। Step 3: Origin distance में signs square होने पर positive हो जाते हैं।
