The volume of the cylinder is the area of the base (a circle) times the height (you can immagine taking a disk, the base, and translate it along the height to "fill" the cylinder).
So you have:
So you have:

opposite side = √91
In quadrant II, value of tan is negative.
Answer:
Step-by-step explanation:
The parametric equations of a circle is
and
The radius of the unit circle is 1 unit.
This implies that any point on the unit circle is represented by:
and
where is the angle in standard position,
From the question, the given angle in standard position is .
This angle intersects the unit circle at
But
We substitute and
