Answer:
V=769.7 cubic feet
Step-by-step explanation:
1) Use the equation
to find the volume of the cylinder
2) Substitute the variables into the equation

3) Use PEMDAS to solve the equation.
4) First square 7 to get 
5) Then multiply the three numbers together to get V

6) Round your answer to the nearest tenth. The 6 would round up since the number after it is greater than 5.
V=769.7 cubic feet
1/2-1/4=1/4
so if you have a half a pound left then you minus the amount you have left from the total you started with and you get 1/4
Answer:
(-2, 0)
Step-by-step explanation:
Answer:
the answer is the first one [3 -12 15 -21]
Step-by-step explanation:
Because 3 times 1 = 3, 3 times -4 = -12, 3 times 5=15, 3 times 7 = -21
because they are in order to get a negative one of them have to be a negative if they both of them where negative it would be positive.
