The edible fruit=fruit-seed

alright

vsphere=4/3pir^3

so if the volume is 100
of the seed
100=\frac{4}{3}\pi r^3
find r
times both sides by 3/4
75=\pi r^3
divide both sides by pi
\frac{75}{\pi}= r^3
cube root both sides
\sqrt[3]{\frac{75}{\pi}}= r
this is the seed radius
3 times of taht is the radius of the fruit
3\sqrt[3]{\frac{75}{\pi}}=radiusfruit

input into equation
use radius fruit for r
V=\frac{4}{3}\pi r^3
V=\frac{4}{3}\pi (3\sqrt[3]{\frac{75}{\pi}})^3
V=\frac{4}{3}\pi (27)(\frac{75}{\pi})
V=\frac{8100\pi}{3\pi}
V=2700 cm^3

so the edible part is 2700-100=2600 cm³
