2000 - 400= 1600 * .10= 160+400= $560 is probably right, but I pretty much guessed on how to get that.
the formula for the circumference of a cirlce is πd. the diameter is 2r which in this case is 0.5. therefore the circumference is 0.5π, or 1.5708 (rounded)

<u>Figure - 1</u> :
Let the missing side as " n "
Therefore the sides will be proportional,

<u>Figure - 2</u> :
Let the missing side as " m "
The Triangles are similar, therefore their sides will be proportional.
