Answer:
4 cm
Step-by-step explanation:
Volume of a cylinder is given by the equation;
[tex]V=\pi r^2 h[/tex]
-Given the volume as 36π and the radius as 3 cm, the cylinder's height can be obtained as;
[tex]V=\pi r^2 h\\\\36\pi=\pi \times 3^2h\\\\36\pi=9\pi h\\\\h=\frac{36\pi}{9\pi}\\\\h=4cm[/tex]
Hence, the height of the new cylinder is 4 cm
