Answer:
2 1/5
2 X 5 + 1 = 11/5
11/5 X 2/1 = 22/5
1 3/4
1 X 4 + 3 = 7/4
7/4 X 2/1 = 14/4
22/5 + 14/4
5 X 4 = 20
4 X 22 = 88
5 X 14 = 70
88/20 + 70/20 = 158/20
20 goes into 158 7 times with 18 left over
7 18/20 simplified = 7 9/10
Volume of a cylinder is pi*(radius)^2* height. pi is 3.14 and radius is half of diameter which would be 3. height is 8. Thus volume of a cylinder in your case is pi*9*8 or 72*pi which is approximately 226.19
