    Do you know the formula to find the volume of sphere? @Kinzol1234

    sphereV= (4/3)(pi)(r^3)

    Vol=4 pi r*r*r/3=k r*r*r (k is a constant) r*2 --> Vol*8 --- 8 times the volume = 7 times larger Not 8 times larger. 8 times as large = 7 times larger.

    (4/3)(22/7)(27) : (4/3)(22/7)(198) (88/21)(27) : (88/21)(198) hope this helped

    r=3 and r1=6 volume of smaller one:volume of bigger one =4pi r *r*r/3 : 4pi r1*r1*r1/3 now cancel whatever got cancelled with eachother now we hvae left only=> r*r*r/r1*r1*r1 now put he values 3*3*3/6*6*6 1/8 i hope u got it now :)

    thank you this makes sense but if we can just cube the number how come there is a formula?
