Three circles, each of radius one, have centres at `A,B` and `C`. Circles `A` and `B` touch each other and circle `C` touches `AB` at its midpoint. The area inside circle `C` and outside circles `A` and `B` is

Three circles with centres A, B and C and with unit radii touch each other at O, P and Q. Find the area of the shaded region .

Draw circles with centres A,B and C each of radius 3 cm, such that each circle touches the other two circles.

Three equal circles of radius unity touches one another.Radius of the circle touching all the three circles is:

Circles of radii 2,2,1 touch each other externally.If a circle of radius r touches all the three circles externally,then r is

Four circles each with radius 2 touches the axes, then the radius of the largest circle touching all the four circles, is

Four circles each with radius 2 touch both axes then the radius of the largest circle touching all the four circles is

In the figure below,the bigger circle has radius xcm with centre at A. Two small congruent circles with centres at B and C touch each other at F and touch the greater circle at D and E respectively.The perimeter of Delta ABC is

Draw circles with centres A, B, C each with radius 3 cm such that each circle touches the remaining two circles.
