Before 1980, Mount St. Helens
was cone shaped with a height of about 1.83 miles
and a base radius of about 3 miles. In 1980.
Mount St. Helens erupted. The tip of the cone was
destroyed, as shown, reducing the volume by
0.043 cubic mile. The cone-shaped tip that was
destroyed had a radius of about 0.4 mile. How
tall is the volcano today? (Hint: Find the height of
the destroyed cone-shaped tip.)
