Question

inner radius is1.5 m and outer radius is 2m and height is2m find the volume of the ring???​

Answer 1

☆ Solution ☆

Given :-

• Inner radius is 1.5 m and outer radius is 2m and height is 2m.

To Find :-

• The volume of the ring.

Step-by-Step-Explaination :-

As we know that :-

Volume ( Ring ) = πh( R² - r² )

Putting the respective value,

Volume = 22/7 × 2 [ (2)² - (1.5)² ]

Volume = 44/7 × [ 4 - 2.25 ]

Volume = 44/7 × 1.75

Volume = 44 × 0.25

Volume = 11 m³

Hence,

The volume of ring = 11 m³.

Answer 2

Given:-

Inner radius = 1.5 m

Outer radius = 2m

Height = 2m.

To Find:-

Volume of the ring.

As we know that:-

Volume ( Ring ) = πh( R² - r² )

Putting the respective value,

Volume = $\rm \dfrac {22}{7}$ × 2 [ (2)² - (1.5)² ]

$\implies \rm \dfrac {44} {7}\: × \: [ 4 \: - \: 2.25]$

$\implies \rm \dfrac {44} {7}\: × \: 1.75$

$\implies$ 44 × 0.25 = 11 m³

Hence,

Volume of the ring = 11 m³
