Answer :
⠀
Explanation :
We know,

Where,
- <em>r</em> is the radius of the cylinder. Here, the radius is 4 cm
- <em>h</em> is the height of the cylinder. Here, height is 6 cm
- Here, we will take the value of π as 3.14 approximately .
⠀
Substituting the values in the formula :
⠀

⠀

⠀

⠀

⠀
Therefore,
- The volume of the cylinder is 301.44 cm³ approximately.
I would say 12 hours and 38 min
Our angle teta is:
teta = 3pi/4
since that is larger than pi/2 but less than pi that means that our angle lies in II quadrant (x negative y positive)
sin(3pi/4) = √2/2
cosine and tangent of that angle must be negative because of position of the angle.
cos(3pi/4) = -√2/2
tan(3pi/4) = -1
