The formula for the area of a cylinder is 
×h
First, we do not have to worry about pi because we are leaving our answer in terms of it so we can move on to the radius squared.
The radius is halfway across a circle so our radius would be 4 and we have to square that and we will get a product of 16.
Lastly, we have to multiply 16 by 8 because 8 is the height of the cylinder
16 × 8 = 128
Therefore, the volume of the cylinder would be 128 in.³
Answer:
x= -3, y=-6
Step-by-step explanation:
In the equation -5x-y=21, substitute y for 6+4x:
-5x- (6+4x) = 21
^^Solve for x.
X should come out to -3. To find y, plug -3 into either equation (-5x-y=21 or y=6+4x) and y should equal -6.
