3 An open cone has a vertical angle measuring 40°
belka [17]

Answer:

13.41 cm

Step-by-step explanation:

The radius, height, and HALF of vertical angle makes a triangle.

Where

Radius will be the base of the triangle

Height will be the "height" of the triangle

Top angle will be HALF of vertical angle (40/2 = 20)

From the 20 degree angle, the side "opposite" would be the radius, which is 30. The side "adjacent" would be the height, let it be h.

<em>Which trig ratio relates opposite and adjacent? Yes, that is TAN. Thus we can write:</em>

Tan(20) = opposite/adjacent

Tan(20) = 30/h

h = 30/Tan(20)

h = 13.41

So

The height of the cone would be around 13.41 cm

A cone with a mass of 6 g has a radius measuring 5 cm and a height of 2 cm. What is its density?
AlekseyPX

Volume of a cone is equal to pi*r^2*(h/3)

3.14*5^2*2/3 = 52.36 cubic cm.

Density = mass/volume

 6 grams/ 52.36 cm^3= 0.1146

Round to 2 decimal places to get D.0.11 g/cm^3

PLEASE HELP!
sesenic [268]

Answer:

36\sqrt{3}

Step-by-step explanation:

Hi!

Since an equilateral triangle means that every side is equal, our triangle will have 12 on all sides.

To find the height of an equilateral triangle we use \frac{a\sqrt{3}}{2}.

\frac{12\sqrt{3} }{2} = 6\sqrt{3}.

So the height is 6\sqrt{3}.

Now we have to solve 12 * 6\sqrt{3} ÷ 2.

12 \cdot 6\sqrt{3} = 72\sqrt{3}

72\sqrt{3}\: \div\: 2 = 36\sqrt{3}.

Thus, the area of the triangle is \boxed{36\sqrt{3}}.

Hope this helps!
