Circumference = pi * diameter
diameter = 8.5; pi = 3.14
C = 3.14 * 8.5
C = 26.69 in = 26.7 in
D = 2r => 12.6 = 2*r => r=6.3
A = π*r^2 = (3.14) * (6.3)^2 = (3.14)*(39.69) = 124.6266 which is approximately 124.63

Answer:
The answer is 41cmHg of pressure.
Step-by-step explanation:
If the volume of the gas is inversely proportional to the pressure that the gas exerts within the defined space that it is in, then for a gas that has a 50cmHg pressure at 9.84 liters of volume, the pressure it will have at 12 liters of volume can be found as Pfinal = (9,84 x 50) / 12 = 41cmHg of pressure for the same gas.
