Question

What is the volume of this sphere with a radius of 9? options> (a)1024π m³ (b) 972π m³ (c)729π m³ (D)81π m³

Answer 1

972π m³

Explanation:

Correct results

Answer 2

Volume of the sphere is
`972\pi\ cm^(3)` .

Option (b) is correct .

Explanation:

Formula

`Volume\ of\ a\ sphere = (4)/(3) \pi r^(3)`

Where r is the radius of a circle .

As given

Sphere with a radius of 9 .

r = 9m

Putting all the values in the formula

`Volume\ of\ a\ sphere = (4)/(3) \pi* 9* 9* 9`

`Volume\ of\ a\ sphere = (4* 9* 9* 9)/(3) \pi`

`Volume\ of\ a\ sphere = (2916)/(3) \pi`

`Volume\ of\ a\ sphere = 972\pi\ cm^(3)`

Therefore the volume of the sphere is
`972\pi\ cm^(3)` .

Option (b) is correct .
