Answer:

h = 3 cm

Step-by-step explanation:

Given that,

Diameter, d = 6 cm

Radius, r = 3 cm

Volume of the cone, V = 28.26 cm³

The formula for the volume of a cone is given by :

V=\dfrac{1}{3}\pi r^2 h\\\\h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 28.26}{3.14\times  3^2}\\\\h=3\ cm

So, the height of the cone is equal to 3 cm.

In triangle MNP, m = 5 cm, n = 4 cm, and p = 8 cm. Which formula can you use to find P?
charle [14.2K]
Answer:
8² = 4² + 5² - 2(4)(5) cos(P)
which is the third option

Explanation:
The general rule of cosine is:
a² = b² + c² - 2bc*cos(A)

In our triangle:
a is substituted by p = 8 cm
b is substituted by n = 4 cm
c is substituted by m = 5 cm
A is substituted by P which we want to find

Replace the variables in the general equation with the givens as follows:
p² = n² + m² - 2mn*cos(P)
8² = 4² + 5² - 2(4)(5) cos(P)

Hope this helps :)

HELPP!!<br> Select the correct answer.<br> What is the value of arcsin ?
Schach [20]

For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.

We must find the arcsin (\frac {\sqrt {2}} {2}). Then, we look for the angle whose sine is \frac {\sqrt {2}} {2}.

We have to, by definition:

Sin (45) = \frac {\sqrt {2}} {2}

So, we have to:

arcsin (\frac {\sqrt {2}} {2}) = 45

Answer:

Option B
