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):

what is ur d LOL:)

anonymous · Answer

5 cm

chmvijay · Answer

Equation is right ? then u r right

anonymous · Answer

YaY! I just found it hard to grasp that it went from 5 to 19.6

chmvijay · Answer

Area= Pie R^2    but R =d/2 
area= Pie R^2/4
ur right LOL:)

chmvijay · Answer

5 is diameter or radius LOL:)
if it is diameter ur right

anonymous · Answer

diameter lol thank you. 
can you help me with the second part?

chmvijay · Answer

its maths question LOL:) why are u posting it here ???

anonymous · Answer

because it was from a chemistry lab
