8 0

Answer:

8 in

Step-by-step explanation:

Use the equation $V=\pi r^2h$ to solve this. You have V=301, pi, and h=6. Solve for r.

$301 = \pi r^2(6)\\\sqrt{ \frac{301}{6\pi }} = r\\r = 3.996$

r is the radius. d is the diameter. The diameter is equal to the radius times two. Double the value you found.

3.996 × 2 = 7.992 ≈ 8

Answer:

θ∈{ $\frac{\pi }{8},\frac{5\pi }{8},\frac{9\pi }{8},\frac{13\pi }{8}$ }

Explanation:

The given equation is

$sin(2\theta )-cos(2\theta )=0$

$\Rightarrow sin(2\theta )=cos(2\theta )\\\\\therefore \frac{sin(2\theta )}{cos(2\theta )}=1\\\\tan(2\theta )=1\\\\\therefore 2\theta =n\pi +\frac{\pi}{4}\\\\\therefore \theta =\frac{n\pi }{2}+\frac{\pi }{8}$

Applying values on 'n' we obtain values of θ that beling to [0,2π)

For n=0, θ= $\frac{\pi }{8}$

For n=1, θ = $\frac{5\pi }{8}$

For n=2,θ = $\frac{9\pi }{8}$

For n=3,θ = $\frac{13\pi }{8}$

72 feet is equal to how many yards?

baherus [9]

Hi there!

Since 1 yd = 3 ft,

72 ft / 3 = ? yd

72 / 3 = 24 yards

So, the answer is 24 yards.

Hope this helps!
