The air pressure in a tire is 150.000 kPa.
The internal surface area of the tire is 1150.000 cm^2. Determine the total force applied by the air to the tire.
(Round to 3 decimal places)
Answer = kN
150.000 kPa x 1000 = 150000 Nm
1150.000 cm / 100 cm = 11.5 m
Force = Pressure x Area
= 150000.000 Nm x 11.5 m
= 172500.000 N
= 172.500 kN
Please Check. Thank you.

cm^2 = m^2/100^2, not m/100
100 cm = 1 meter
Is 172.500 kN correct?
Is 172.500 kN correct?
yes, but 10,000 cm^2 = 1 m^2
Pascals are in the MKS system. No cm allowed. Everything is in meters.
