If the volume of a hemisphere is 2,712.3 in^3, what is the radius??

V hemisphere   = (2/3)pi (radius)^3

 

2,712.3  = (2/3)pi (radius)^3   divide both sides by (2/3)pi

 

[ 2,712.3 ]  / [ (2/3) pi ]    =  radius^3     take the cube root of both sides

 

( [ 2,712.3 ]  / [ (2/3) pi ] ) ^(1/3)   = radius  = about  10.9 in
