Question

c)
The diameter of sphere is 5m. Calculate the surface area and volume of the sphere. (pai = 3.14)
​

Answer 1

Answer :

• Volume of sphere = 523.3cm³

Given that :

• The diameter of sphere is 5m

To find :

• Volume of the sphere

Solution :

To find the volume of the sphere , first to find the radius after we need to use the formula of volume of sphere ,

As we know that

• Volume of sphere = 4/3 πr³

Where ,

• r is radius

➨ Volume of sphere = 4/3 πr³

➨ Volume of sphere = 4/3 × 3.14 × (5)³

➨ Volume of sphere = 4/3 × 3.14 × 5 × 5 × 5

➨ Volume of sphere = 4/3 × 31.4 × 125

➨ Volume of sphere = 4/3 × 392.5

➨ Volume of sphere = 523.3 cm³

Hence , Volume of sphere = 523.3 cm³

More Explanation :

• Surface area of sphere = 4πr
• Volume of sphere = 4/3 πr³
• Sphere does not have any sides and surfaces
• A sphere is a round shape
