Below are two views of a computer model of a cinder cone volcano. This particular volcano has a diameter of
150 m at the top of the volcano, 450 m at the outside base of the volcano and the interior diameter at the base
is 80 m. The volcano is 230 m tall. Find the approximate volume of the earth materials that make up the
volcano. Use different shapes to create a composite that approximates the volume of the volcano. Then
calculate the volume of your composite. Explain your reasoning using words and drawings for why you chose
the shapes and measurements in your composite. Be sure your final answer has units with it! Round your
answer to the nearest tenth.
