The radius of a sphere of lead (B= 4.2 ×10¹⁰N/m²) is 1.000m on the surface of earth where the pressure is 1.01 × 10° N/m². The sphere is taken by submarine to the deepest part of the ocean to a depth of 1.10 × 10⁴ m where it is exposed to a pressure is 1.25 × 10⁸ N/m². What is the volume of the sphere at the bottom of the ocean?​
