Answer: 414.48

Step-by-step explanation:

r: the radius of the base

h: height

The volume of a cone is given by:

V = π ∙ r2 ∙ h / 3,

where π ∙ r2 is the base area of the cone.

π defines the ratio of any circle's circumference to its diameter and is approximately equal to 3.141593, however the value 3.14 is often used.

Question:

The angle $\theta_1$ is located in Quadrant III, and $sin(\theta_1) = - \sqrt{\frac{3}{2}}$ .

What is the value of $cos(\theta_1)$ ?

Express your answer exactly. $cos(\theta1) =$ ________

Answer:

$cos(\theta_1) = - \frac{1}{2}$

Step-by-step explanation:

Given:

$sin(\theta_1) = - \sqrt{\frac{3}{2}}$

Since the angle $\theta_1$ is located in Quadrant III, we have:

$sin(\theta_1) = sin(\pi + \frac{\pi}{3})$

$\theta_1 = \pi + \frac{\pi}{3}$

$\theta_1 = \frac{4 \pi}{3}$

Thus, $cos(\theta_1)$ =

$cos(\theta_1) = cos(\pi + \frac{\pi}{3})$

$cos(\theta_1) = -cos(\frac{\pi}{3})$

$cos(\theta_1) = - \frac{1}{2}$

<h3><u>Answer</u> :</h3>

It is clear from the diagram that,

ㄥ6 + ㄥ8 = 180

⇒ (2x - 5) + (x + 5) = 180

⇒ (2x + x) + (5 - 5) = 180

⇒ 3x + 0 = 180

⇒ x = 180/3

⇒ x = 60°

◈ From the geometry of figure,

ㄥ3 = ㄥ6

⇒ ㄥ6 = (2x - 5)

⇒ ㄥ6 = (2×60 - 5)

⇒ ㄥ6 = 120 - 5

⇒ <u>ㄥ6 = 115°</u>
