A.180 millimeter
B.18 millimeters
C.4500000 millimeters

So, x/9000 = 1/500

x = 9000/500

x = 18

In short, Your Answer would be 18 mm [ Option B ]

Answer 2

Let, the diameter in drawing = x

So, x/9000 = 1/500
x = 9000/500
x = 18

In short, Your Answer would be 18 mm [ Option B ]

Hope this helps!
