The height will be 4 cm.
Explanation
<u />The volume of a cylinder is given by the formula V=πr²h. For a volume of 36π cm³ and a radius of 3 cm,
36π = π(3²)h
36π = 9πh
Divide both sides by 9π:
36π/9π = 9πh/9π
4 = h
Step-by-step explanation:
The answer is
4_

9_

Use Pythagorean thrm
17^2+10^2=21^2
289+100=441
389≠441
This is not a right triangle
