Question

Please help find the volume of this sphere as soon as possible.. I really don’t understand how to do this..

Answer 1

What do we know from the problem?:

*the fourmula

* the radius= 7cm

*To use 3 for Pi

All we have to is plug what we know into the formula:

*do go in order so you don't mess yourself*

V= 4/3 x 3 x 7³

4/3 x 3= 4

7³= 343

4 x 343= 1,372cm³

Answer 2

1372

`(4)/(3) \pi r^(3)`

`(4)/(3) \pi 7^(3)`

7*7*7 = 343

4/3 * 3 * 343 =

4* 343

1372
