Answer:
B. 
Step-by-step explanation:
We are told that the smallest object visible with our eyes is similar to the width of a piece of hair, which is
meters wide.
Using an optical microscope, we can see items up to
meters wide.
To find the objects we can see with our eyes are how much larger than the objects we can see with an optical microscope, we can set an equation as:

Using the exponent rule of quotient
we will get,





Therefore, the objects we can see with our eyes are
times larger than the objects we can see with an optical microscope and option B is the correct choice.
It is given that
.
Now, know that in 180 degrees there are
radians. This can be written as:
radians
radians (dividing both sides by 180)
Thus, to find the measure of the given angle of
in radians, we will have to multiply the above equation by 135. Thus, we get:
radians
radians
Thus, equivalent to the radian measure of angle a is 2.356
