1995.7 cm³

Step-by-step explanation:

To find the volume of a cylinder we have to utilise the formula π × r² × h

where 'r' is the radius and 'h' is the height. In this question we are only given the diameter but we can half that to find the radius so 11 ÷ 2 = 5.5. So the radius of the cylinder is 5.5 so,

Volume = π × r² × h

→ Substitute in the values

Volume = π × 5.5² × 21

→ Simplify

Volume = 1995.69673

So the volume of this cylinder is 1995.7 cm³
