The radius of a cylindrical construction pipe is 2ft. if the pipe is 19ft long, what is its volume? use the value 3.14 for π, and round your answer to the nearest whole number. be sure to include the correct unit in your answer.

239 ft³

Step-by-step explanation:

Multiply the squared radius by π:

2*2*3.14=12.56 ft².

Multiplying the height:

12.56*19≅239 ft³.

answer: -8.2562234e+13

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
