What is the volume of this sphere?

 

Use 3.14 for pi and round to the nearest hundredth when necessary.

 

113.04 cm³

678.24 cm³

904.32 cm³

7234.56 cm³

Using the forumla, 4/3 pi r^3, we have 4/3*3.14*216=904.32cm^3, so the third option.

radius   =   diameter / 2   =   12 cm / 2   =   6   cm

 

volume of sphere   =   4/3 * π * radius3

volume of sphere   =   4/3 * π * (6 cm)3

volume of sphere   =   4/3 * π * 216 cm3

volume of sphere   =   288π  cm3

volume of sphere   ≈  288(3.14)  cm3   =   904.32  cm3
