Question

Find the volume of a hollow sphere having outer radius 3 cm and inner radius 2 cm.
1. 72/3 Π
2. 67/3 Π
3. 57/3 Π
4. 76/3 Π

Answer 1

Correct Answer - Option 4 : 76/3 Π

Given:

Hollow sphere having outer radius 3 cm and inner radius 2 cm

Formula Used:

Volume of hollow sphere = 4/3 × Π [R³ – r³]

Where, R = outer radius, r = inner radius

Calculation:

Volume of hollow sphere = 4/3 × Π [R³ – r³]

= 4/3 × Π [3³ – 2³]

= 4/3 × Π [27 - 8]

= 4/3 × Π × 19

= 76/3 Π
