Sorry, I meant what was the value and the formula used to get 67428900 meters^2?The shockwave reaches america, both the cross sectional area of a half sphere and cylinder are a circle and both would be the same value (a shockwaves at ground level expands as a half sphere, cloud formations expand in a cylinder hence the two versions) its the total distance of the shockwaves because doing otherwise for the initial would be incorrect here for how this calc works
