Question

A cylinder boiler is 2m high and has 3.5m radius . find its volume

Answer 1

Volume of cylinder = πr²h

= 22/7 × (3.5)² × 2

= 22/7 × 3.5 × 3.5 × 2

= 22 × 0.5 × 3.5 × 2

= 77m²

Hope it helps.........✌

Answer 2

Answer:

Volume of cylinder =πr²h

=22/7×3.5×3.5×2

=22/2×3.5×2

= 11 ×3.5×2

= 77m²

Step-by-step explanation:

The volume of cylinder is 77m²
