Question:

a basketball is inflated to 9.0 psi (pounds per inch) above atmosphere pressure of 14.7 psi ( a total pressure of 23.7 psi). The diameter of the basketball is 10inches.
What is the pressure of the air in the basketball, expressed in atmospheres?

Answers

1 pound per square inch = 0.0680459639 atm

So,

Pressure of the air in the basketball = 23.7*0.0680459639 = 1.612689344.
