The formula for the area of a cone using slant height is:  A  =  pi · radius · slant height

--->     10.4·pi  =  pi · 1.3 · slant height

--->         10.4  =  1.3 · slant height                                 (divide by pi)

--->              8  =  slant height                                          (divide by 1.3)
