Volcano

The crater of a volcano is approximately in the shape of a cone of a base 3.1416 sq. Mi. The crater's depth is 1500 ft. How many cubic yards of earth would be required to fill this cavity?

Correct result:

x =  1621903360 yd3

Solution:

S=3.1416 3097600=9731420.16 yd2 h=1500 ft yd=1500/3  yd=500 yd  x=13 S h=13 9731420.16 500=1621903360 yd3=1.622109 yd3

Why did you multiply the base by 3097600 and why did you divide the height by 3 .
