The diameter of the base of the cone measures 8 units. The height measures 6 units. A cone has a diameter of 8 units and a heigh

Brilliant_brown [7]

Answer: V = 100.48

Step-by-step explanation:

To get this value, you need to know the formula of the volume of the cone, which is:

V = π*r^2*h / 3

Where:

r: cone radius

h: height

π: value of pi which is 3.14

Now the radius, is half the diameter of base of the cone so:

r = 8 / 2 = 4 units

Now we have all the data needed to get the volume of the cone, let's use the expression given above:

V = 3.14 * (4)^2 * 6 / 3

V = 3.14 * 16 * 6 / 3

V = 301.44 / 3

V = 100.48

Express the polynomial z2 − z4 + 2z2 in standard form and then classify it.

Inessa05 [86]

The answer in standard form is
-z^4 + 3z^2
This is a quartic polynomial

The term with the highest exponent is listed first, then you list the next largest and so on. The like terms are z^2 and 2z^2 which combine to 3z^2

Use long division to determine the decimal equivalent of fraction with numerator 2 and denominator 3. 0 point 6 bar 0 point 7 ba

VikaD [51]

Answer:

The correct answer is A

$0.\bar6$

Step-by-step explanation:

We want to determine the decimal equivalence of $\frac{2}{3}$ .

We perform the long division as shown in the attachment.

Note that in carry out the long division, the denominator which is 3, will be outside the long division sign, while the numerator which is $2$ , will be inside the long division sign.

We see that the quotient of our long division is $0.6666...$ .

We can rewrite this as $0.\bar6$

Therefore $\frac{2}{3}=0.\bar6$ .

What is the equation of the graph below

aksik [14]

Answer:

The answer is B) y = Sin(3x)

Step-by-step explanation:

In order to find this, you need to look for how long it takes the period to repeat. This means other than the origin, we need to find the next place that the graph hits y = 0. In this case, it is at 2 $\pi$ /3. Since Sin2 $\pi$ = 0, we need what is inside of the parenthesis to equal 2 $\pi$ .

The only thing that you could multiply 2 $\pi$ /3 by to get 2 $\pi$ m is 3. Therefore, we must have 3x in the original equation.
