Question

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 approximate pi, and express your final answer as a decimal. Enter your answer as a decimal in the box. In³.

Answer 1

The approximate volume of the model will be

$v=452.33 inch^{2}$

What is the approximate volume of the model?

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  $v=452.33 inch^{2}$
