The formula to find the volume of a cylinder is V=h so you would first have to find the radius which would be 11 because half of 22 is 11 and the radius is half of the diameter. You would replace r with 11 and replace h with 18 so you should have V=18 and then you just solve it. You should get V≈6842.39
The relation between the width and the length is:
l = 3w + 1 --- (1) Perimeter = 2w + 2l --- (2) Put (1) in (2) » Perimeter = 2w + 2(3w+1) » Perimeter = 2w + 6w + 2 Perimeter = 8w +2
