Answer:
Option B
Step-by-step explanation:
A unit circle means radius of the circle = 1 unit
Let a terminal point on the circle is (x, y) and angle between the point P and x-axis is θ.
Center of the circle is origin (0, 0).
Therefore, ordered pair representing the terminal point will be (OP×Cosθ, OP×Sinθ) = 
OP.Cosθ = 1×Cosθ = 
Cosθ =
θ =
,
where n = integers
Similarly, OP×Sinθ = 1×Sinθ = -
Sinθ = -
θ =
,
where n = integer
Common value of θ will be, θ = 
Option B will be the answer.

Volume of the cylinder is 3696 m²
Step-by-step explanation:
- Step 1: Calculate volume of the cylinder using the formula V = πr²h
⇒ V = 22/7 × 14² × 6 = 3696 m²
3y-12=-30
3y=-30+12
3y=-18
y=-18/3
y=-6.
