Question #e696b

Answer 1

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

Explanation:

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).
