Answer:
For the first one its: Volume = 402.12in³
For the second one its: Volume = 201.0619 in³
Step-by-step explanation:
For the first one work:
Volume = 3.1416 x 42 x 8
= 3.1416 x 16 x 8
For the second one work:
Volume = 3.1416 x 42 x 4
= 3.1416 x 16 x 4
-78
Step-by-step explanation:
(7-8)(78)
(-1)(78)=-78
Since, the co-interior angles(55° and 125°) are supplementary(sum is 180), therefore the lines are parallel.
Point-slope form is 
, where 
is the slope and 
is a point on the line.
Substitute in the values. 
Simplify the negative subtraction to addition. 
C. [-1 10 0 -9 1 8]
B. [0 -6 3 4 1 -4]
