What is the approximate volume of a sphere with a radius of 12 ft? Use 3.14 to approximate pi and express your answer in hundredths. ft3 @Nnesha

Nnesha (nnesha):

same formula

OpenStudy (anonymous):

the other was wrong oddly

Nnesha (nnesha):

this time you have to use pi

Nnesha (nnesha):

OpenStudy (anonymous):

*makes gurgling noises*

OpenStudy (anonymous):

OpenStudy (anonymous):

huhahuba

Nnesha (nnesha):

OpenStudy (anonymous):

18

OpenStudy (anonymous):

4/3*pi*r^3

OpenStudy (anonymous):

but wasnt that the radius?

Nnesha (nnesha):

how that be the answer ?? impossible

Nnesha (nnesha):

yes 18 is the radius

OpenStudy (anonymous):
