The top of the surface is in the shape of a annulus with a outer radius of 10 mm and a inner radius of 7 mm ( since the diameter of the hole is: 14 mm and we know that the radius is half of the diameter)
Now, we know that the area of the annulus region is given by:

where R is the outer radius and r is the inner radius.
Here we have:

Hence, we have:

Step-by-step explanation:
A = 25% of 16 =
Selling price after reduction = 16 - 2 = $14
B= 25% of 14

= 3.5
Selling price = 14 - 3.5 = $10.5
C = 25% of 10.5

= 2.625 = $ 2.63
Selling price = 10.5 - 2.63 = $ 7.87
