Answer 2

Answer:

draw the perpendicular from centre on the cord AB that bisect in two equal part.i.e.2

apply formula

1/2 *b*h=1/2*4*2√3=4√3

or

radius =4

cord=4

and third side of triangle is also 4 i.e.radius

therefore we can apply area of equilateral triangle formula

.i.e.√3/4*side2

=√3/4*4*4

=4√3
