Question

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800 cubic centimeters. Which equation can be used to find the area of the circular base?

Answer 1

For this case we can model the problem as a cylinder.
 The volume of a cylinder is given by:
 $V = Ab * h$
 Where,
 Ab: base area
 h: cylinder height
 Substituting values in the equation we have:
 $800 = Ab * 46$
 From here, we can clear the area of the base
 Answer:
 An equation that can be used to find the area of the circular base is:
 $800 = Ab * 46$
