he crater of a volcano is approximately in the shape of a cone of base 3.1416 sq. mi.
Convert sq miles to sq yds. 3.1414 * 3.098(10^6) = 9732676.8 sq yds
The crater's depth is 1,500 ft.
convert to yards, 1500/3 = 500 y
How many cubic yards of earth would be required to fill this cavity?
:
the volume of a cone, 1/3 * base area * height
V = *9732676.8 * 500
V = 1,622,112,800 cubic yards of earth
