Answer:
V = 486
, or approx. 1,526.814
Step-by-step explanation:
V = 
*r²*(h/3)
plug in the numbers: V = 
 * (9)² * (18/3)
simplify: V = 
 * 81 * 6
simplify: V = 486
, or approx. 1,526.814
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Sinθ = 
If, sinθ = -
 and π < θ < 
Since, sinθ is negative, angle θ will be in IIIrd quadrant.
And the measure of angle θ will be (180° + 30°) 
θ = 210°
It's necessary to remember that tangent and cotangent of angle θ in quadrant III are positive.
Therefore, cos(210°) = 
tan(210°) = 
csc(210°) = 
sec(210°) = 
cot(210°) = √3
 
        
             
        
        
        
Answer: (v + 7)(v -3)
Step-by-step explanation:
(v +7)(v -3)
v x v = v^2
v x -3 = -3v
7 x v = 7v
7 x -3 = -21
v^2 -3v +7v -21 = v^2 +4v -21 = 0
