A seamless spherical shell, 90cm in diameter and 1 cm thick, is being filled with a fluid under pressure until its volume increase by 150cm3. Calculate the pressure exerted by the fluid on the shell, taking modulus of elasticity (E) for the material of the shell as 2×105MPa and Poisson’s ratio ($\mu$) as 0.3
