Step 1
To convert from atm to mmHg, we can use the conversion factor: 1 atm = 760 mmHg. So, the pressure of the NBA basketball in mmHg is: 0.544 atm * 760 mmHg/atm = 413.44 mmHg Show more…

The recommended air pressure in a basketball is between 7 and 9 pounds per square inch (psi). When dropped from a height of 6 feet, a properly inflated basketball should bounce upward between 52 and 56 inches (http://www.bestsoccerbuys.com/balls-basketball.html). The basketball coach at a local high school purchased 10 new basketballs for the upcoming season, inflated the balls to pressures between 7 and 9 psi, and performed the bounce test mentioned above. The data obtained are given in the following table. Pressure (psi): 7.8, 8.1, 8.5, 7.3, 8.7, 7.2, 8.7, 7.5, 8.1, 8.3 Bounce height (inches): 54.1, 54.3, 55.2, 53.3, 55.4, 52.2, 55.7, 54.6, 54.8, 55.3

An inflated basketball has a gauge pressure of $74 \mathrm{kPa}$. What is the actual pressure inside the ball?
A basketball is inflated to 9.0 psi above atmospheric pressure of 14.7. The diameter of the basketball is 9.8 inches. What is the total pressure of the air in the basketball, expressed in atmospheres?
