V = 16 pi h

Step-by-step explanation:

If the diameter is 8, the radius is d/2 =4

The volume is given by

V = pi r^2h

V = pi (4^2)h

V = 16 pi h

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
