Question

Calculate the surface area of the circle (πd2/4) with a diameter of 5cm:
3.14*5^2/4=19.6
Can someone help me find is this is accurate? If not, what am I doing wrong?
Calculate the surface area of the dishwashing circle to molecules per layer (this requires converting the surface area from meters to nanometers)
Thanks for any help.

Answer 1

that is the surface area.

"Calculate the surface area of the dishwashing circle to molecules per layer "

i dont understand what this is trying to say

Answer 2

My thoughts exactly.

Answer 3

i think they might mean:

"Convert the surface area of the circle to molecules per layer"

..if they gave you a size for a molecule.
