Which of the following distances is the shortest? 0.007 km 0.2 cm 30 mm 580 mm

Option (b) is the correct answer.

Explanation:

Since, all the given distances are present in different units. So, convert them into same unit.

As there are 1000 meter present in 1 kilometer so, we convert all of them into meter as follows.

                           = 7 m

There are 0.01 m present in 1 cm.

So,     = 0.002 m

There are 0.001 m present in 1 mm.

So,     = 0.03 m

        = 0.58 m

Thus, we can conclude that out of the given options shortest distance is 0.2 cm.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.
