I've seen the other question about surface areas. I still don't understand the lateral area. In my math book, it has (pi * r * L) as the equation, r = radius and L = height of the cone. This is 8th grade math. Thanks. |
Hi Michael,
The lateral area of a cone is 
r L where r is the radius but L is the slant height. Look at what Walter wrote to respond to a similar question a while ago.
