I have a question so here I go.

Given the formula r=(3v/4pi) 1/3; calculate r if V=1000 cm3.

I did this math but not too sure if it's right, my answer is 785.39.

is V=v? they aren't usually in math so i ask
i get a diff ans but i don't think the formual is rite
is this 4 a sphere? cuz that's V=(4/3)(pi)(r^3) so

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

cbrt[3V/4pi]=r

it's to the 1/3 power not time 1/3.
but i still don't get your ans sry
