For this case we have that by definition, the density is given by:
Where:
M: It is the mass
V: It is the volume
According to the data of the statement we have:
So, the mass is given by:
Thus, the mass of the brass ornament is
Answer:

. Local extrema occur when
and the sign of
changes to either side of that point.
is positive when
is between -4 and some number between -2 and -1, and also 2 (exclusive) and 4, so you can estimate that
is increasing on the intervals [-4, -2] and (2, 4].
is negative when
is between some number between -2 and -1, up to some number less than 2. So
is decreasing on the interval [-1, 1].
You then have two possible cases for extrema occurring. The sign of
changes for some
between -2 and -1, and again to either side of
.

Assuming that R is angle R, and O is angle O, your answer is 58° because the angle at the centre is twice the angle at the circumference.
(Sorry about the confusion!)
It is 8,138,64 because the 6 is in the tenths place and compared to 265.47 it is 100 times smaller then it because it is 2 decimal places apart.
