Question

The diameter of a sphere is 6 cm, the
volume of sphere will be:​

Answer 1

Answer:

d=6

r=volume of sphere=4/3×22/7×3×3×3=113•14

Answer 2

Given

We have given diameter of sphere which is 6cm

To find

We have to find the volume of sphere

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

How to solve

Step1: Firstly we will find radius of sphere by using diameter.

Step2:Then will apply formula for volume of Sphere

Step3:Radius we find and hence evaluate it your required volume.

Diameter of sphere= 6cm

We know that Diameter is twice of radius or radius is half of Diameter.

So,radius will be = D÷2= 6÷2=3

Radius =3cm

Now, applying formula for finding volume

volume of sphere =4/3πr³

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$=113.14cm³

Hence,volume of sphere is 113.1cm³

Extra information=>

• Volume always written in cubic units.
• Since,the sphere is a curved shape figure so,it's curved surface area is equal to the total surface area is 4πr²

More about sphere

• A sphere is a curved shape figure means it has no flat surface.
• Also,it has no edges nor vertices .
• It's surface points are at equidistant from its centre.
