The numbers would quickly become ridiculous if that 13000 was the increase in diameter. A 13000 times increase in diameter means roughly 2.197.000.000.000 times increase in volume

Volume is based on diameter too. Mass is the density times its volume. Assuming similar mass distribution with earth (not very likely for something that massive though
) any increase in volume is directly proportional to the increase in mass.
A more specific reason why 13000 times the size does not equal 13000 times the mass is because different layers have different densities. Generally, it gets denser the closer you go to the core, one of the reason being temperature and pressure. A 13000 times increase in volume mean about 24 times increase in diameter. That's DEEP, the temperature and pressure at the core would be astronomical and the density values would be unbelievable long before you even reach the core.
So yeah, it's probably very likely that this planet would collapse onto itself if it exists in real life
