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 in the box.

in³

Answer 1

ur welcome ;)

Answer 2

Let’s use the formula of a cylinder

\[V = \pi r^{2} h\]

Where V is the volume of the cylinder, r is the radius, and h is the height. They give us the diameter. Half the diameter is the radius, so we divide 10 by 2 and we get 5.

\[V = \pi (5^{2})(10)\]

\[V = 785.4 \]

Be sure to add in^3
