The volume, V, of a sphere in terms of its radius, r, is given by V(r)=43r3. Express r as a function of V, and find the radius of a sphere with volume of 500 cubic feet.

Round your answer for the radius to two decimal places.

Enclose numerators and denominators in parentheses. For example, (ab)/(1+n).

Include a multiplication sign between symbols. For example, a*.
