Question

find the volume of sphere having radius 4.5cm. [π=3.14]​

Answer 1

Step-by-step explanation: V = 4 /3πr3 = 4 /3*π*4.53≈381.70351 cm³

Answer 2

Answer :

• Volume of sphere is 381.7 cm³

Given :

• Radius = 4.5cm

To find :

• Volume of sphere

Solution :

As we know that,

• Volume of sphere = 4/3πr³

where, r is radius 4.5cm and π is 3.14

》Volume of sphere = 4/3πr³

》4/3 × 3.14 × (4.5)³

》4/3 × 3.14 × 4.5 × 4.5 × 4.5

》381.7 cm³

Hence , Volume of sphere is 381.7 cm³

More Explanation :

• Surface area of sphere = 4πr²
• Diameter of sphere = 2r
• Volume of sphere = 4/3πr³
