2/3

Step-by-step explanation:

-2/3

Step-by-step explanation:

Each mark on the number line is 1/3 unit.

Start at 1 2/3. That is the rightmost mark just before the right arrow.

You must subtract 2 1/3 units from it.

To subtract, you go left on the number line.

Every three marks you go left, you are subtracting 1 unit.

Go 3 marks to the left. That means subtracting 1 unit. Now you are at 2/3.

Now go another 3 marks to the left. You subtracted another unit. You are now at -1/3.

You still need to subtract 1/3, so go 1 more mark to the left. You arrive at -2/3. You have subtracted 2 1/3 from 1 2/3. The answer is -2/3.

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.
