Answer:
volume: [tex]\sf 16\pi x^3y^4[/tex]
given:
- height: [tex]\sf 4xy^4[/tex]
- radius: [tex]\sf 2x[/tex]
cylinder volume:
[tex]\hookrightarrow \sf \pi r^2h[/tex]
[tex]\hookrightarrow \sf \pi (2x)^2(4xy^4)[/tex]
[tex]\hookrightarrow \sf \pi (4x^2)(4xy^4)[/tex]
[tex]\hookrightarrow \sf 16\pi x^3y^4[/tex]
