Question 18: (8 points) The volume, V, of a sphere in terms of its radius, r, is given by V (r) = gar. Express , as a function of V, and find the radius of a sphere with volume of 300 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 * *. T (V) = A sphere with volume 300 cubic feet has radius feet. Show your work and explain, in your own words, how you arrived at your answers
