The slant height would be 10.63014581, or rounded to 10.6 or even 11. Sorry, I thought you knew about the Pythagorean Theorem (a^2 + b^2 = c^2). :( Anyways, hope this helps ;)
*February 25, 2015*

**math help!!!!! Thanks**

Callie, you don't need division I believe. Multiply pi by the radius and that by the slant height. That counts as the lateral area. Then multiply pi by the radius-squared. Add those together. Remember the slant height is not the same as the height, so use the Pythagorean ...
*February 25, 2015*

**math help!!!!! Thanks**

SA = Lateral Area + Base Area SA= (pi X radius X slant height) + (pi X r^2) To find the slant height, use the Pythagorean Theorem. Let me know if you need more help, it is no trouble at all :)
