Question

What is the volume of the sphere that has a diameter of 3? use 3.14 for pie​

Answer 1

Hey ! there

Answer:

• 113.04 unit cube

Explanation:

In this question we are provided with a sphere having radius 3 units and value of π is 3.14 . And we're asked to find the volume of sphere .

For finding volume of sphere , we need to know its formula . So ,

`\qquad \qquad \: \underline{\boxed{ \frak{Volume_((Sphere)) = (4)/(3) \pi r {}^(3) }}}`

Where ,

• π refers to 3.14

• r refers to radius of sphere

Solution : -

Now , we are substituting value of π and radius in the formula ,

`\quad \longrightarrow \qquad \: (4)/(3) * 3.14 * (3) {}^(3)`

Simplifying it ,

`\quad \longrightarrow \qquad \: (4)/(3) * 3.14 * 3 * 3 * 3`

Cancelling 3 with 3 :

`\quad \longrightarrow \qquad \: \frac{4}{ \cancel{3}} * 3.14 * 3 * 3 * \cancel{3}`

We get ,

`\quad \longrightarrow \qquad \:4 * 3.14 * 9`

Multiplying 4 and 3.14 :

`\quad \longrightarrow \qquad \:12.56 * 9`

Multiplying 12.56 and 9 :

`\quad \longrightarrow \qquad \: \pink{\underline{\boxed{\frak{113.04 \: unit \: cube}}}} \quad \bigstar`

• Henceforth , volume of sphere having radius 3 units is 113 .04 units cube .
