The formula for this is an easy, straightforward one: [tex]A= \pi rl[/tex] where r is the radius and l is the slant height. You have your area and your radius, so solve it for slant height. [tex]587= \pi 32l[/tex] and [tex]l= \frac{587}{32 \pi } [/tex]. Multiply that pi in to the 32 and then divide that into 587 and you'll get 5.8
