Calculate the surface area of the circle (πd2/4):

3.14*5^2/4=19.6

Is that right?

If it is-

Calculate the surface area of the dishwashing circle to molecules per layer (this requires
converting the surface area from meters to nanometers):

I'm not sure what this problem is about.  The area of a circle is pi r^2 but yes, that would be the same as squaring the diameter and dividing by 4 although I'm not sure what the point would be.

mertsj · Answer

And I don't know if your answer is right because I don't know what the diameter is.

anonymous · Answer

I know the top part is right, I just need help with the second part..

anonymous · Answer

diameter is 5

mertsj · Answer

Is the diameter 5 meters or what?

anonymous · Answer

sorry 5 centimeters.

mertsj · Answer

So the area is 19.6 cm^2

mertsj · Answer

So why does it say we have to convert the area from meters to nanometers?  Could you please post the ENTIRE problem?

anonymous · Answer

can I give you the link o the page because it is pdf and wont let me copy paste it all.

mertsj · Answer

ok

So all you have to do there is the arithmetic.  They have it all set up for you.

anonymous · Answer

yeah I don't know if I am supposed to add, multiply, or divide...in between the sets
