Solution:

Given that,

A model of a volcano has a height of 12 in., and a diameter of 12 in.

We know that, volcano is of shape cone,

The volume of cone is given as:

Where,

r is the radius

h is the height

From given,

h = 12 inches

Diameter = 12 inches

Substituting the values we get,

Thus volume of model is 452.16 cubic inches

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
