Answer the question please it’s 21 points it’s just 7 and 8

7. volume is raised to the third (a³) power.

8.≈ 5.64ft

Step-by-step explanation:

volume is always raised to the third power which also indicates that the object/shape is cubed.

height= 4ft

volume= 100ft³

then, multiply both the height and volume together.

4ft × 100ft³

≈ 5.64ft

answer: i can’t tell you that

step-by-step explanation:

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
