Question

NFL regulations require all footballs to be inflated to between 12.5 and 13.5 psi. One football was found to have a pressure of 84.3 kPa. If 1 psi is equal to 8.895 kPa, what is the pressure of this ball in psi?

Answer 1

The pressure of the football is approximately 9.479 psi when converted from 84.3 kPa using the conversion factor of 1 psi being equal to 8.895 kPa.

Step-by-step explanation:

To convert the pressure from kilopascals (kPa) to pounds per square inch (psi), we can use the conversion factor where 1 psi is equal to 8.895 kPa. The formula for this conversion is:

Pressure in psi = Pressure in kPa / Conversion factor (8.895 kPa/psi).

Using the provided information, the pressure of the football in psi is:

Pressure in psi = 84.3 kPa / 8.895 kPa/psi = 9.479 psi (approx).

Therefore, the football's pressure of 84.3 kPa is approximately equivalent to 9.479 psi.
