Ten points `P, Q.....,Y` are equally spaced around a circio of radius one unit, then what is difference in the length of the line `PQ and PS?`

A line with positive direction cosines passes through the point P(2,1,2) and makes equal angles with the coordinate axes.The line meets the plane 2x+y+z=9 at point Q. The length of the line segment PQ equals

Ten equally spaced point are lying on a circle, if p is the probability that a chosen chord is diameter of the circle, then 18p+2 is equal to ______.

Ten equally spaced point are lying on a circle, if p is the probability that a chosen chord is diameter of the circle, then 18p+2 is equal to ______.

A line with positive direction cosines passes through the point P (2, - 1, 2) and makes equal angles with the coordinate axes. The line meets the plane 2x + y + z = 9 at point Q. The length of the line segment PQ equals:

A line with positive direction cosines passes through the point P(2, – 1, 2) and makes equal angles with the coordinate axes. The line meets the plane 2x + y + z = 9 at point Q. The length of the line segment PQ equals
