 | | The formulae for all regular polygons and the circle is the same herein, and only the ratio of pi is varied to match the appropriate polygon. |
 | | One half the base circumference times the slant height S, will result in the area of the lateral surface. |
 | | But, instead of r times C and dividing by two__ we multiply poly pi times r (instead of d), which gives immediately one half circumference, and then simply multiply times the lateral slant height line S, for lateral surface area. |
