Answer:
Therefore the mass of the of the oil is 409.59 kg.
Step-by-step explanation:
Let us consider a circular disk. The inner radius of the disk be r and the outer diameter of the disk be (r+Δr).
The area of the disk
=The area of the outer circle - The area of the inner circle
=
Since (Δr)² is very small, So it is ignorable.
∴
The density
We know,
Mass= Area× density
Total mass
Therefore
= 409.59 kg (approx)
Therefore the mass of the of the oil is 409.59 kg.
