enyata [817]

Answer: 6 cm

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:  

Volume of a cylinder (V): π x radius ² x height  

Replacing with the values given and solving for v (Volume)  

1584 = π x r ² x 14

Solving for r:

1584 / (π x 14) = r²

36.01 = r²

√36.01 = r

6 cm = r

In conclusion, the radius of the cylinder is 6 centimeters.

Feel free to ask for more if needed or if you did not understand something.
