there is a circle which circumscribes three unit circle which are tangential to each other what is the circumference of

wat r the options??
my answer is pi(4+2sqrt3)/sqrt3
is it the correct answer?

radius of bigger circle= (2+ sqrt3)/sqrt3
area of circle= 3.14* ((2+ sqrt3)/sqrt3)^2 =14.59

@ Ahkhil after drawing the figure now radius of bigger circle=
=radius of 1 unit circle + distance between vertex of equilateral triangle to centroid(since it is the centre of bigger circle)=1+2*sqrt(3)/3

dran an equiltrl traingle by joining all 3 centre of the internal circles
x=sqrt(2sq-1sq)
x=1.73
finl radius of bigger circl is 1+1.73=2.73
finl circumfrnc =2*2.73*pie=5.46

plzzzz elaborate it further??? how to proceed after joining the centers of the circles forming equilateral triangle??

radius of bigger circle=(2/sqrt3)+1;area=pi((2/sqrt3)+1)^2=14.59
