# what name for a shape made from two intersecting circles of different sizes?

what is the name of a shape made from two circles with different radii that intersect each other?

Sort of like a snowman shape, made of a big and a small ball of snow, melted together a bit! :-) Thanks

May I hazard a guess? ... Snowman? –  Raskolnikov Apr 29 '11 at 20:19
One interrogation and one exclamation symbol are more than enough. –  Arturo Magidin Apr 29 '11 at 20:20
While a snowman from the West would be the intersection of three circles, the shape you describe is the silhouette of a Japanese snowman. –  buruzaemon Apr 29 '11 at 22:15
Don't you mean union? –  quanta Apr 29 '11 at 23:17

FWIW: the (usual) lemniscate (Bernoulli, Gerono) is not a union of two circles. One can however specialize the hippopede $r^2=4b(a-b\sin^2\theta)$ to the case $a=b$... –  J. M. is back. Apr 30 '11 at 0:16
