The dimensions of the bottom of the drawer are:
20 cm × 40 cm
So the area is : 800 cm² (rectangular shaped)
The area formula of a circle is:

r²
The diameter of the plate is 20cm
so the radius is half the diameter which is 10cm
Apply the given to the formula:

(10)²
100

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
171.68 cm²

y=2x
</span><span>What would the x equal</span>
Answer:
86 - 3x
Step-by-step explanation:
1- Calculate
2x + 4y = 38......multiply by -5
10x + 3y = 105
-----------------
-10x - 20y = - 190....result of multiplying by -5
10x + 3y = 105
----------------add
-17y = - 85
y = -85/-17
y = 5
2x + 4y = 38
2x + 4(5) = 38
2x + 20 = 38
2x = 38 - 20
2x = 18
x = 18/2
x = 9
solution is : (9,5)
