Answer 1

Given (√3/4)a²=121√3
                     a = 22cm
∴ length of wire= perimeter of the triangle = 3a
                           = 66cm

Perimeter of circle ⇒2πr=66
                                         r= 21/2

Area =πr²
         =πx21/2x21/2
         =346.5

Area enclosed by the circle is 346.5 sq cm
