A model of a volcano has a height of 12 in. , and a diameter of 12 in. What is the approximate volume of the model? Use 3. 14 to

jenyasd209 [6]

The approximate volume of the model will be

$v=452.33 inch^{2}$

<h3 /><h3>What is the approximate volume of the model? </h3>

It is given that

$Height of the volcano =12 inch$

$Diameter of the volcano= 12inch=r=6inch$

So the volume of the model will be =

$=\dfrac{1}{3\\} \pi \times r^{2} \times h$

$= \dfrac{1}{3} \pi \times (6)^{2} \times 12$

$v=452.33inch^{2}$

Thus the approximate volume of the model will be $v=452.33 inch^{2}$

To know more about the volume of the cone follow

Solve -5/3x + 7/3 = -5

Pavlova-9 [17]

Answer:

x = 24/15 = 8/3 = 2 2/3

Step-by-step explanation:

remember what you do to the left you must do to the right.

I converted the -5 to -15/3 so I could easily add or subtract

-5/3 x = -8/3

multiply both sides by -3/5 to cancel the coefficient of the x

x = -8/3 * -3/5 = 24/15
