Question

The volume of a cylindrical vessel is 770 cm*3 if its radius is 7cm then find its height and area of the base

Answer 1

Answer:

Volume of cylinder = π r² h = 770 cm³

given it's radius is 7cm

So, 770 = ( 22/7 ) × 7 × 7 × h

770 = 154 × h

770 / 154 = h

5cm = h

It's height is 5 cm

Area of base = Volume of cylinder / Height of cylinder = 770 / 5 = 154 cm²

Answer 2

Step-by-step explanation:

Answer:

Volume of cylinder = π r² h = 770 cm³

given it's radius is 7cm

So, 770 = ( 22/7 ) × 7 × 7 × h

770 = 154 × h

770 / 154 = h

5cm = h

It's height is 5 cm

Area of base = Volume of cylinder / Height of cylinder = 770 / 5 = 154 cm²
