Answer:

the volume of the inside of half grapefruit is ( 128/3) pi the volume of 1 of the 12 segments is (32/9) pi

Step-by-step explanation:

The volume of half a sphere (hemisphere) is (2/3) pi r^3  

(2/3) 4^3 pi = (2/3)(64)pi = (128/3) pi  -

The volume of one of the 12 segements is the answer divided by 12
