Find the volume of the cone, read the directions carefully!!

Answer:

300 units^3 or 96π

Step-by-step explanation:

Volume of the cone would be:

Because the formula of finding the volume of cone is

V = πr^2 * h/3

r is the radius of the base

h is the height of the cone

π is Pi, approximately 3.142 and it is the circumference of any circle divided by its diameter

V is volume

So in this case:

V = πr^2 * h/3

V = π * 6^2 * 8/3

V = π * 36 * 8/3

V = 96π or 301.44 and round it up to 300 units^3

Hope this help :3

Find the angles between -pi and pi that satisfy:<br><br> (−√3) sin(v)+cos(v)=√3

MAXImum [283]

Observe that

$\sin\left(\dfrac\pi6-v\right)=\sin\dfrac\pi6\cos v-\cos\dfrac\pi6\sin v=\dfrac12\cos v-\dfrac{\sqrt3}2\sin v$

In the original equation, divide both sides by $\dfrac12$ :

$-\sqrt3\sin v+\cos v=\sqrt3\implies\dfrac12\cos v-\dfrac{\sqrt3}2\sin v=\dfrac{\sqrt3}2$

$\implies\sin\left(\dfrac\pi6-v\right)=\dfrac{\sqrt3}2$

Next,

$\sin x=\dfrac{\sqrt3}2\implies x=\dfrac\pi3+2n\pi,x=\dfrac{2\pi}3+2n\pi$

where $n$ is any integer. Then

$\sin\left(\dfrac\pi6-v\right)\implies v=-\dfrac\pi6-2n\pi,v=-\dfrac\pi2-2n\pi$

Fix $n=0$ to ensure $-\pi$ , so that

$v=-\dfrac\pi6,v=-\dfrac\pi2$
