Coordinates Of A Point In Space

Let the vertices of triangle be and . Here,
Therefore, it is an equilateral triangle. So, the in centre coincides with centroid.

The correct answer is B:2
The curve equation;

and
we can represent it in the form;
={
From the above Plotted figure;
QA=QB=OC=OD=1 units
units
Hence, area bounded by the region sq.units
