The length of the perpendicular drawn from the point P(a, b, c) from z-axis is(a) a2+b2(b) b2+c2(c) a2+c2(d) a2+b2+c2

The length of the perpendicular drawn from the point P(a, b, c) from z

1.	The length of the perpendicular drawn from the point P(a, b, c) from z-axis is(a) a2+b2(b) b2+c2(c) a2+c2(d) a2+b2+c2
Answer» The length of the perpendicular drawn from the point P(a, b, c) from z-axis is (a) $\sqrt{a^{2} + b^{2}}$ (b) $\sqrt{b^{2} + c^{2}}$ (c) $\sqrt{a^{2} + c^{2}}$ (d) $\sqrt{a^{2} + b^{2} + c^{2}}$
