Step-by-step explanation:
Given that, volume of the cylinder is 660 cm³ and radius of the cylinder is 5 cm.
Let,
Height of the cylinder = h cm
Formula used :
Volume of cylinder = πr²h
According to the question,
πr²h = 660
→ 22/7 × 5×5×h = 660
→ h = 660×(7/22)×(1/5)×(1/5)
→ h = 8.4
Therefore, the height of the cylinder is 8.4 cm.
