The air pressure in a tire is 800.000kPa.The internal surface area of the tire is 550.000cm^2. Determine the total force applied by the air to the tire. (Round to 3 decimal places).

ANS = 44.000kN

Force = Pressure x Area
= 800.000kPa x 550.000
= 440000.000N
= 440.000kN

I keep making the same mistake. Please let me know what I am doing wrong. I can't figure how to get the right answer of 44.000kN.

1kPa = 1000 N/m^2

Your area is 550 cm^2, not m^2
Gotta get the proper units.

Unfortunately, it still doesn't look like it works out.

I think the answer must be 44N, not 44kN.

To determine the total force applied by the air to the tire, you need to multiply the pressure (in kilopascals) by the area (in square centimeters). Let's go through the steps again to see where the mistake might lie.

In the given problem, the air pressure in the tire is 800.000 kPa, and the internal surface area of the tire is 550.000 cm^2.

First, let's convert the area from square centimeters to square meters, as pressure is typically measured in pascals (which is equivalent to newtons per square meter).

Since 1 square meter is equal to 10,000 square centimeters, the area in square meters is:

550,000 cm^2 ÷ 10,000 = 55 square meters

Now, let's calculate the force:

Force = Pressure x Area

Force = 800.000 kPa x 55 m^2

Note that 1 kPa equals 1,000 Pa (pascals).

Therefore, the force is:

800.000 kPa x 1,000 Pa/kPa x 55 m^2

Calculating this gives us:

= 44,000,000 N

To convert the force from newtons to kilonewtons (kN), we divide by 1,000:

= 44,000 kN

So the correct answer is indeed 44.000 kN.

It seems like you made a mistake by not converting the area from square centimeters to square meters. Be careful with the units and conversions, as they can greatly impact the result.
