The dimensions of the bottom of the drawer are:
20 cm × 40 cm

So the area is : 800 cm² (rectangular shaped)

\pir²
The diameter of the plate is 20cm
so the radius is half the diameter which is 10cm
Apply the given to the formula:
\pi(10)²
100\pi
314.16 cm²

2 plates in the bottom drawer
Area of two plates:
2 × 314.16
628.32 cm²

Area of the non-covered space in the bottom drawer:
Area of drawer - area of two plates
800 - 628.32
