$800 = Ab \times46$

Step-by-step explanation:

For this case we can model the problem as a cylinder.

The volume of a cylinder is given by:

$V = Ab \times h$

Where,

Ab: base area

h: cylinder height

The volcano is 46 centimeters tall and has a

volume of 800 cubic centimeters.

Substituting values in the equation we have:

$800 = Ab\times 46$

From here, we can clear the area of the base

An equation that can be used to find the area of the circular base is:

$800 = Ab \times46$
