Area of lens?
Trying to understand the Prime and got stuck in the Geometry app looking for a quick and
easy way to measure the area of two intersecting circles. Am I blind and stupid or is the feature not available? I know how to do the long version with triangles and stuff to get the area but was expecting something more userfriendly and timesaving since the Prime has enough muscles to do the calculations in a wink of an eye.

RE: Area of lens?
I don't think I've ever seen any geometry software that will do this in one step. I don't see how you'd be able to define the syntax for such an operation...
TW Although I work for the HP calculator group, the views and opinions I post here are my own.

The formula is described here: mathworld
Intersections and other parameters for the circles are easy to find as you specify them when they are created and any point that exists in both circles are on the inside of the lens. Area calculations are already available for graphs in the "Signed area" feature.
