To determine the volume of the oil drop, we need to find the radius of the circular part covered by the oil drop.

The diameter of the circular part is given as 20 cm, so the radius is half of that, which is 20/2 = 10 cm.

The oil drop has a diameter of 0.05 cm, so the radius of the oil drop is 0.05/2 = 0.025 cm.

Now, we can calculate the volume of the oil drop using the formula for the volume of a sphere:

Volume = (4/3) * π * r^3

where r is the radius of the oil drop.

Plugging in the values, we get:

Volume = (4/3) * π * (0.025)^3

= (4/3) * π * 0.000015625

≈ 0.000065449 cm^3

Therefore, the volume of the oil drop is approximately 0.000065449 cm^3.

The diameter of the circular part is given as 20 cm, so the radius is half of that, which is 20/2 = 10 cm.
