The formula [tex]$P=\frac{F}{A}$[/tex], where [tex]$P=$[/tex] pressure, [tex]$F=$[/tex] force, and [tex]$A=$[/tex] area, is used to calculate pressure. Solve this formula for [tex]$F$[/tex].

A. [tex]$F = P - A$[/tex]
B. [tex]$F = P + A$[/tex]
C. [tex]$F = \frac{P}{A}$[/tex]
D. [tex]$F = P A$[/tex]

To solve the formula [tex]\( P = \frac{F}{A} \)[/tex] for [tex]\( F \)[/tex]:

1. Start with the given formula:
[tex]\[ P = \frac{F}{A} \][/tex]

2. To isolate [tex]\( F \)[/tex], we need to eliminate the fraction. We can do this by multiplying both sides of the equation by [tex]\( A \)[/tex]:
[tex]\[ P \cdot A = \frac{F}{A} \cdot A \][/tex]

3. Simplifying the right side of the equation, since [tex]\( \frac{F \cdot A}{A} = F \)[/tex]:
[tex]\[ P \cdot A = F \][/tex]

4. Rearrange the equation to solve for [tex]\( F \)[/tex]:
[tex]\[ F = P \cdot A \][/tex]

Thus, the correct solution for [tex]\( F \)[/tex] in terms of [tex]\( P \)[/tex] and [tex]\( A \)[/tex] is:
[tex]\[ F = P \cdot A \][/tex]

The correct answer among the given options is:
[tex]\[ F = P A \][/tex]
