From which of the following the distance of the point (1, 2, 3) is √10
Origin
x-axis
y-axis
z-axis
Distance from origin √1+4+9=√14and from y-axis = √1+9=√10.
Find the point on y-axis which is at a distance of √10 units from the point (1, 2, 3)
Find the points on z-axis which are at a distance √21 from the point (1, 2, 3)
