Answer:  (2) 1650 cm³

Explanation:-
Given-
Height of the cylinder = 21 cm & radius of the cylinder = 5 cm

Formula-
The volume of the circular cylinder = π r²h

Where, r = radius of the cylinder & h= height of the cylinder.

Then volume of the cylinder = 22 x 5 x 5 x 21/7
= 22 x 25 x 3
= 1650 cm³

Hence, the correct answer is option (2) 1650 cm³.
