The radius of a spherical balloon is 1/2 foot. the radius of a second one is 3/4 foot. how do the volumes of the balloons compare?

V = (4/3) r^3

first one

V = (4/3) (1/2) ^3

V=4/24

V=1/6

V = (4/3) (3/4) ^3

V=108/192

V=9/16

compare

1/6 to 9/16

16/96 compared to 54/96

well, the bigger ballon is 19/8 ft^3 bigger than smaller oe
