282.7 mm³

EXplanation
To get the volume of the given figure, we should calculate the volume of the inner part and subtract it from the volume of the outer part.

Volume of the inner part = πr²h = π × 1.5² × 9 = 63.62 mm³ 
Volume of the outer part = π × 3.5² ×9 =346.36 mm³

volume of the figure = 346.36 - 63.36 = 282.74 mm³
The correct answer is c) 282.7mm³
