Answer:

<em>V = 65.9 cubic millimeters</em>

Step-by-step explanation:

<u>The Volume of a Right Circular Cone</u>

Given a right circular cone of radius r and height h, its volume is calculated as follows:

\displaystyle V=\frac{1}{3}\pi r^2h

The cone shown in the image has a radius of r=3 mm and a height of h=7 mm, thus the volume is:

\displaystyle V=\frac{1}{3}\pi\cdot 3^2\cdot 7

Taking pi as 3.14:

\displaystyle V=\frac{1}{3}3.14\cdot 3^2\cdot 7

Calculating:

V = 65.9 cubic millimeters

I can't find x y or z​
Sholpan [36]

Answer:

x = 4\sqrt{3}

y = 6

z = 8

Step-by-step explanation:

keep in mind I'm not doing that well with geometry so this might all be wrong lol

x is part of a 30 60 90 triangle.

so x is 4\sqrt{3}

next, this is a right angle triangle so you can follow the a^2 + b^2 = c^2 formula.

4 + 6 = 10

10^2 = 100

100 = a^2 + b^2

y = 6 and z = 8 bc 36 + 64 = 100

HELPP ASAPP<br><br> How many solutions does the equation 2x + .5y = -4 have?
Rashid [163]

Answer:

Topics

2x-5y=4. 2x−5y=4. Add 5y to both sides. Add 5y to both sides.

2x=4+5y. 2x=4+5y. The equation is in standard form. The equation is in standard form.

2x=5y+4. 2x=5y+4. Divide both sides by 2. ...

\frac{2x}{2}=\frac{5y+4}{2} 22x​=25y+4​ Dividing by 2 undoes the multiplication by 2. ...

x=\frac{5y+4}{2} x=25y+4​ Divide 4+5y by 2.

Step-by-step explanation: How do I determine how many solutions an equation has?

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.
