At a mere 3032 miles across (diameter), Mercury is now the smallest of the planets due to the planet Pluto being demoted to a "dwarfplanet".

Assuming Mercury is a sphere,its surface area,in square miles,is easily calculated from its radius of 1516 miles.The formula is 4 times"pi" times theradius squared. Using 3.14159 as the value for "pi":

the surface area ofMercury is 4 x 3.14159 x 1516 x 1516 square miles.

That's about 28,880,710 square miles.
