Two circles with centers `A` and `B` and radius `2` touch each other externally at `C. A` third circle with center `C` and radius `2` meets the other two at `D,E` Then area `ABDE` is

Two circles with centers A and B and radius 2 units touch each other externally at 'C' and radius 2 units meets other two at D and E. Then the area of the quadrilateral ABDE is :

If two circles S=0 and s'=0 are touch each other externally then

Two circles with centres C_(1),C_(2) and same radius r cut each other orthogonally,then r is

A circle centered at P with radius 4cm and another circle centered at Q with radius 16cm toucheach other externally.A third circle with centre Ris drawn to touch the first two circles and oneof their common tangents as shown in the figure.Then,the radius of the circle with centre R is:
