Question
Find the distance between the pairs of points:
(2, 3, 5) and (4, 3, 1)
Advertisements
Solution
The distance between points P(x1, y1, z1) and P(x2, y2, z2) is given by
= `sqrt((x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2)`
Distance between points (2, 3, 5) and (4, 3, 1)
= `sqrt((4 - 2)^2 + (3 - 3)^2 + (1 - 5)^2)`
= `sqrt(2^2 + 0^2 + (4)^2)`
= `sqrt(4 + 16)`
= `sqrt20`
= `2sqrt5`
