Eva pumps up her bicycle tire until it has a gauge pressure of 413 kilopascals. If the surrounding air is at standard pressure,
KIM [24]

The tire pressure is the sum of gauge pressure and the standard pressure of atmospheric pressure

We know that the standard air pressure of surrounding = 101.325 kPa

The given gauge pressure = 413 kPascal

So the tire pressure =  101.325 kPa + 413 = 514.325 K Pa

We can also convert the given pascals to atmosphere or Torr or mmHg or bar
