It is very easy if x is the diameter, then the magnified length is 1000x.
ince 1000x=0.5 then x=0.5/1000=0.0005.

Diameter of circular piece of tissue is \(0.5\) cm when magnified \(1000\) times.

Actual diameter of circular piece of tissue without magnification would be \(= \frac{0.5}{1000} = 0.0005\) cms

Answer (D)...
