Answer:
56.5 in^2
Step-by-step explanation:
The volume of a cone is π
h/3. The radius is d/2=6/2=3
V=(3.14 x
x 6)/3
=(3.14 x 54)/3
=169.56/3
=56.52
Answer:
It is true, because the cosine function has a period of 2π
Step-by-step explanation:
Since, the period of the cos function is 360° ( or 2π radians ), it holds the property of:
![Cos(\theta)=Cos(2\pi +\theta)](https://tex.z-dn.net/?f=Cos%28%5Ctheta%29%3DCos%282%5Cpi%20%2B%5Ctheta%29)
Taking
as
,
is equal to ![2\pi + (-\frac{\pi}{2})\\=2\pi - \frac{\pi}{2}\\=\frac{4\pi-\pi}{2}\\=\frac{3\pi}{2}](https://tex.z-dn.net/?f=2%5Cpi%20%2B%20%28-%5Cfrac%7B%5Cpi%7D%7B2%7D%29%5C%5C%3D2%5Cpi%20-%20%5Cfrac%7B%5Cpi%7D%7B2%7D%5C%5C%3D%5Cfrac%7B4%5Cpi-%5Cpi%7D%7B2%7D%5C%5C%3D%5Cfrac%7B3%5Cpi%7D%7B2%7D)
The equation is true!
<u>Note:</u> The cos function is even function
Hence, the equation is true, because the cosine function has a period of 2π, NOT because the cosine function is ODD, which it is not!!
Answer:
?
Step-by-step explanation:
the choices, the question?
1 liter= 1 dm³=1000 cm³
230 cm³ = 0.23 dm³ = 0.23 lit.
If 1 gal= 3.79 lit.:
3.79 : 0.23 = 16.478 glasses of milk
