Answer:

3V

r = ∛ ( ---------- )

Explanation:

Please, enclose the fraction 4/3 inside parentheses, to eliminate any possibility of misreading this fraction. Also note that this formula MUST include "pi," symbolized by π.

V = (4/3) π r³ This formula does NOT include "m," which is a unit of measurement, not a variable.

Our task is to solve this formula for the radius, r.

Divide both sides by (4/3) π, to isolate r³. This results in:

v (4/3) π r³

------------- = -----------------

(4/3) π (4/3) π

V 3V

Then r³ = -------------- = --------

(4/3) π 4π

and r is found by taking the cube root of the above result:

3V

r = ∛ ( ---------- )
