# If the size of the fruit is two times the size of the seed. Then what is the volume of the seed. (derive general equation)

#### integral

seed diameter : 2x

fruit diameter : 4x (because the size of fruit is two times the size of the seed)

seed volume : 3/4*pi*x^3

fruit volume : 3/4*pi*(2x)^3

seed volume : fruit volume = x : 8x

so general equation is 8(seed volume) =  (fruit volume)

1/2 times of the fruit

Lets assume the fruit to be spherical in shape.

So, volume of seed = (4/3) (pi) (r^3)
volume of fruit   = (4/3) (pi) ((2r)^3)
(volume of seed/volume of fruit) = (1/8)

So, the general formula is:
8*(volume of seed) = 1*(volume of fruit)

I think I am right. If not, pardon me.

Volume of a circle is = area*area*area
So the Volume of the seed is 6.
