The Lateral Area of a cone, or the curved wrapping of the cone, can be found by this formula: 
The "r" stands for radius length, and the "l" stands for slant height (that is the official symbol). We are given that the radius length is 8 so we can plug that in.
The slant height is 17. (Slant height is the distance from the vertex point of a cone to any point on the circumference of its circle base).
8x17

I'm not quite sure what DP is, but if it means exact value leave the pi symbol. Pi is the ratio of the circumference to the diameter, so 3.14 is not necessarily the most exact in all circles. Hope this helps!
