If sin θ = 1 over 3 and tan θ < 0, what is the value of cos θ? (1 point)

Illusion [34]

$\sin\theta=\dfrac13>0$ , so

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}$

Recall that

$\cos^2\theta+\sin^2\theta=1$

for all $\theta$ , and knowing that $\cos\theta$ we have

$\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac{2\sqrt2}3$

Radius = 8 ft; Height = 7 ft<br> What is the volume

Goshia [24]

Answer:

volume = 1,407.4 cubic feet

= 200.96

volume = 200.96 x 7

= 1,407.4 cubic feet
