Answer:

2.40 kPa

Explanation:

Given data:

radius or width of the cylinder d= 9.7 cm

radius r= 4.85 cm

height h= 12 cm

force applied from the piston F= 18 N

Area of the cross section of cylinder A=πr^2

= \pi (0.0485)^2= 0.007386 m^2

now, pressure P= Force / Area

P= \frac{18}{0.007386}

= 2437.04 \frac{N}{m^2}

= 2.437 kPa

correct to two significant figure = 2.40 kPa
