Water at 30 C is pumped into a spherical tank of diameter 2 m, and pumping is stopped when the water just fills the tank.

Water at  30 C is pumped into a spherical tank of diameter 2 m, and pumping is stopped when the water just fills the tank. According to manufacturer's specifications, the tank can withstand an internal gage pressure of up to   10 MPa. What additional mass of water could be pumped into the tank without the tank failing?

Can you help me with this answer immediately ?
