If the standard pressure in a car tire is 38 psi, what is the force exe
the tire if the area of the tire is 12 cm by 18 cm? Round your answ
pound.

1272 pound

Explanation:

From the question given above, the following data were obtained:

Pressure (P) = 38 psi

Area (A) = 12 cm by 18 cm

Force (F) =?

Next, we shall determine the area. This can be obtained as follow:

Area (A) = 12 cm by 18 cm

A = 216 cm²

Next, we shall convert 216 cm² to square inch (in²). This can be obtained as follow:

1 cm² = 0.155 in²

Therefore,

216 cm² = 216 cm² × 0.155 in² / 1 cm

216 cm² = 33.48 in²

Finally, we shall determine the force exerted. This can be obtained as follow:

Pressure (P) = 38 psi = 38 lbf/in²

Area (A) = 33.48 in²

Force (F) =?

P = F/A

38 = F / 33.48

Cross multiply

F = 38 × 33.48

F = 1272 pound

Thus, the force exerted is 1272 pound

the answer is c.the valence of the atoms combine .
