What is the circumference of the circle?

1) 2 by 6 rectangle is inscribed in circle

2) 5 by 5 square is inscribed in circle

3) 5 by 6 rectangle is inscribed in circle

4)2 by 15 rectangle is inscribed in circle

5) 1 by 12 rectangle is inscribed in circle

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
