The compressibility of a material is

If a spherical ball contract in volume by 1% under a normal uniform pressure of 200 atmophere, then the compressibility of the material of the ball is (1 atmosphere = 10^(5) Nm^(-2) )

If compressibility of material is 4xx10^(-5) per atm, pressure is 100 atm and volume is 100 cm^(3) then find triangleV=?
