THREE 2 INCH DIAMETER TENNIS BALLS SNUGLY FIT IN A CYLINDRICAL CAN. THE BALLS TOUCH THE SIDE, TOP AND BOTTON OF THE PLASTIC CAN. HOW MUCH AIR IS IN THE CAN? ROUND DECIMAL ANSWERS TO THE NEAREST TENTH OF A CUBIC INCH. SHOW OR EXPLAIN HOW YOU GOT YOUR ANSWER.

Answer 1

First, do not use all capitals. It is harder to read and is equivalent to SHOUTING online.

Volume of cylinder 6" high and 2" in diameter minus volume of three balls, each with a 1" radius.

Cylinder volume = pi * r^2 * h

Sphere volume = 4/3 pi * r^3

You can do the calculations.
