Given,
Force, F=450 N
Area is
[tex]A=0.08\text{ m}^2[/tex]To find
The pressure on the piston
Explanation
The pressure is
[tex]\begin{gathered} P=\frac{F}{A} \\ \Rightarrow P=\frac{450}{0.08} \\ \Rightarrow P=5625\text{ N/m}^2 \end{gathered}[/tex]Conclusion
The pressure is
[tex]5652\text{ N/m}^2[/tex]
