27500 people live in the Duchy of Grand Fenwick, which has a land area of a square 5.8 km on each side. How many people live there per square km?

One of the exoplanets in the TRAPPIST-1 System recently discovered has a radius larger than that of Earth by a factor of 1.13. How much bigger is the surface area of this planet than Earth? [SA=4(pi)(r^2)]

Toward the end of their lives, many stars become much bigger. assume that they remain spherical in shape and that their masses do not change in this process. If the radius of a star increases by a factor of 11.4, by what factor does its CIRCUMFERENCE change? [C=2(pi)r]
