A spherical gas-storage tank with an inside diameter of 29 ft is being constructed to store gas under an internal pressure of 218 psi. The tank will be constructed from structural steel that has a yield strength of 38 ksi. If a factor of safety of 3.0 with respect to the yield strength is required, determine the minimum wall thickness required for the spherical tank.
