Answer:

56.55 units

Explanation:

If we rotates this rectangle we will get a cylinder.

The base of this cylinder is a circle with a radius of 3 units (the high of the rectangle).

And the high of this cylinder is 2 units.

Volume of cylinder is given by the formula :

V= h.pi.r²

so V= 2×3.14×9

= 56.55 units
