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

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
