A sphere with a radius of 1.7cm has a surface area of? a) ##3.6*10^-3 m^2## b) 36 m c) 3.66mm

a) ##3.6*10^(-3) m^2##

a) is the only possibly correct answer since the other two have units which are not areas (both ##m## and ##mm## are linear measures).

We can verify the area using the Surface Area formula ##color(white)("XXX")A = 4pir^3##

The only possible trick here is in converting between ##cm^3## and ##m^3## (or maybe handling scientific notation).
