pls solve it on a page.​

Answer 1

Step-by-step explanation:

Let the O,A,B,C be the center of the circumscribing circle, and three touching circles respectively.

Area of ΔABC=43×a2

21×2×BD=3

BD=3

BO=32×BD

BO=32×3

BO=323

So, radius of circumscribing circle is =1+OB

=1+323

=33+23

Therefore, Area of circumscribing circle =πr2

=π(33+23)2

=3π(2+3)
