Answer:
The correct answer is option A
Step-by-step explanation:
The volume of a cylinder is given by

Substituting the values of radius and height in above equation, we get -

Recall that
and
for all
. So


For
, we expect both
and
(i.e. the sine and cosine of any angle that lies in the first quadrant must be positive). By definition of absolute value,
if
.
So we have

making H the answer.
C is always true, because the inequality reduces to x > y.
Mass error is due to temperature which is a random error. I believe.
