Acan of tuna has a shape similar to the shape of a large water tank. the can of tuna has a diameter of 3 inches and a height of 2 inches. the water tank has a diameter of 6 yards. what is the height of the water tank in both inches and yards? explain.

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
