A frustum of a cone is that part of the surface of a cone between two planes perpendicular to the axis of the cone; if a cone has base radii r1 and r2 and slant height h, then its area, A is given byA = 2*pi*h*(r1+r2)/2cited from Varberg and Purcell's Calculus textbook, 9ed.; p299.
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
If the diameter doubles (x2), the cross-sectional area quadruples (x4).
Other things being equal, more cross-sectional area will cause less resistance.
Because the volume of the cylinder is proportional to the cross sectional area of the cylinder. The cross sectional area is a circle and the area of a circle is pi*r2.
Cross Sectional Area = Width x Average Depth
the average of the projected surface areas

You cannot create a cross sectional area of a rectangle. You can only create cross sectional areas for triangular shapes.
To calculate Cross Sectional Area: Width x Depth
the larger the cross sectional area, the smaller the resistance
Volume = cross sectional area * lengthArea = 2* cross sectional area + perimeter of cross section * length
The cross sectional area of a slab can be found by squaring the height of the slab.
cross-sectional area = 0.5*(sum of parallel sides)*height
reduction ratio= initial cross sectional area/final cross sectional area
cross sectional area of cable * voltage drop
The answer depends on whether the cross sectional radius/diameter are doubles or the cross sectional area is doubled.
