Hi,

The volume of a gas in a container at a constant temperature varies inversely as the pressure.

 V = k/P

The volume is 26 cubic centimeters at a pressure of 11  pounds.

 26 = k/11

 26*11 = k = 286

when the volume is 43 cubic centimeters, find pressure (it will be less as Volume increases)

  P = k/V = 286/43 lbs

(Answer is between 6 and 7)

Will Let You finish the exact arithmetic with Your Calculator.. 

Rounding off Your answer, according to instructions(not given here)

Wish You the Best in your Studies.
