Question

The volume of cylinder can be 1.5litre and area of its base is 77 . find its height​

Answer 1

20.07 cm³

Explanation:

Volume of Cylinder = 1.54 liters = 1540 cm³.

Area of its base = 77 cm².

πr² = 77

(22/7) * r² = 77

r = 4.94

Now,

Volume of cylinder = πr²h

⇒ 1540 = (22/7) * (4.94)² * h

⇒ h = 20.07 cm³
