The volume, V, of a sphere in terms of its radius, r, is given by V (r) = A7773. Express 7' as a function 3 of V, and nd the radius of a sphere with volume of 400 cubic feet. Round your answer for the radius to two decimal places. Enclose numerators and denominators in parentheses. For example, (a b) / (1 + n). Include a multiplication sign between symbols. For example, a * 7r. r(V): BEE A sphere with volume 400 cubic feet has radius Number feet
