Detailed Solution

The volume of a cylinder shaped solid is 1584 cm3 and its height is 14 cm. Then, its radius is 6 cm.
Given, the volume of a cylinder shaped solid is 1584 cm3 and its height is 14 cm.
We know that the volume of a cylinder is πr2h=1584.
πr2(14)=1584
r2=158414π
r2=36
r=36=6 cm
So, the radius is 6 cm.
Hence, the correct answer is 6 cm.
