ans1.6 =>

angle of equilateral triangle = 60

 

area of circlular arc = (60/360)*pi(a/2)2 = pia2/24

 

here we have 3 arcs so total area = 3(pia2/24) = pia2/8

 

area of equilateral triangle = a2root3/4

 

area of triangle - area of circle = remaining

 

pia2/8 - a2root3/4 = a2/8[pi-2root3]

 

option a) is correct
