transposition of formula help?

Question

Make r the subject of the equation: v = 4πr³/3

Answer 1

(3V/4pi)^(1/3)=r

you could express that term "3V/4pi" as cube root

Answer 2

cube root of (3v/4pi)= r

that's my answer

see, I assumed the 3 was dividing the whole 4pir^3 thing, so I timesed that off to the other side

that would make 3v and leave the other stuff on the other side

to get rid of 4pi, since it is timsing, you must divide it off of each side

so you get 3v/4pi = r^3

and the only way to get rid of 3 squared is to take a cube root of each side.

and voila, r is alone.

it's like what will said.

Answer 3

You want to rewrite this so it is r=something

r^3=3v/(4π)

r = [3v/(4π)]^(1/3)
