A cone has a radius of 4 units and a height of 6 units. Its volume is (A. 96 / B. 100.48 / C. 301.44 / D. 401.92) cubic units. I

Fed [463]

Answer:

<h2>A cone: B. V = 100.48 cubic units</h2><h2>A cylinder: C. V = 301.44 cubic units</h2>

Step-by-step explanation:

The formula of a volume of a cone:

$V=\dfrac{1}{3}\pi r^2H$

<em>r</em> - radius

<em>H</em> - height

We have <em>r = 4 u</em> and <em>H = 6 u</em>. Substitute:

$V=\dfrac{1}{3}\pi(4^2)(6)=\dfrac{1}{3}\pi(16)(6)=\dfrac{1}{3}\pi(96)=32\pi\ u^3$

$\pi\approx3.14\to V\approx(32)(3.14)=100.48\ u^3$

If the cylinder has the same radius and height as a cone, then the volume of the cylinder is three times larger than the volume of the cone.

Therefore, the volume of acylinder:

$V\approx3(100.48)=301.44\ u^3$

Why?

The formula of a volume of a cone:

$V_{cone}=\dfrac{1}{3}\pi r^2H$

The formula of a volume of a cylinder:

$V_{cylinder}=\pi r^2H$

Therefore

$V_{cone}=\dfrac{1}{3}V_{cylinder}\to V_{cylinder}=3V_{cone}$

If the radius and height are the same.

Write each of the following expressions without using absolute value. |z−6|−|z−5|, if z<5

Andre45 [30]

Answer: 6 - 5

<u>Step-by-step explanation:</u>

|z - 6| - |z - 5| ; z < 5

Since z < 5, then

|z - 6| will be the absolute value of a negative number. Replace the absolute value with a negative and parentheses:

-(z - 6) = -z + 6

|z - 5| will be the absolute value of a negative number. Replace the absolute value with a negative and parentheses:

-(z - 5) = -z + 5

Now subtract them without the absolute value signs:

-z + 6 - (-z + 5)

Distribute the negative sign:

-z + 6 + z - 5

-z + z = 0 which leaves:

6 - 5

Is -24 a solution to the equation -16+2x=-64

S_A_V [24]

Answer:

It is a solution

Step-by-step explanation:

To check and see if it is a solution, we can substitute it in

-16 +2(-24) = -64

-16 -48 = -64

-64=-64

Since this is true, it is a solution
