The exact values of the cotangent and the cosine of the angle are 
and 
, respectively.
According to the information given, the angle resides in the <em>first</em> quadrant of the Cartesian plane. Hence, the cosine and the cotangent of the angle are also positive.
By trigonometry we remember the concepts of sine, cotangent and cosine:
(1)
(2)
(3)
Where 
.
If we know that 
and 
, then the cotangent and the cosine of the angle are, respectively:
The exact values of the cotangent and the cosine of the angle are and , respectively.

Answer:
(1/3) Pi r^2 h
Step-by-step explanation:
The volume of a cone (or pyramid, for that matter) is 1/3 the area of the base times the height.
Cones have bases that are circles, so their areas are Pi r^2, usually written 
, Pi times the radius squared.
Answer:
6 units
Step-by-step explanation:
(6, -3) is 6 units towards the right of the y-axis
So, the shortest distance of (6, -3) from the y-axis is 6 units
