Javon wanted to make a homemade exercise ball by pouring sand into a ball. he purchased 729 cubic inches of sand and wants to figure out the radius of the largest exercise ball that he could make. he will do this by solving the volume equation of a sphere for the radius. v = 4 3 πr3 after dividing the volume by π, javon is unsure of the next two steps to solve for r. complete the table to determine two possible next steps that he could do to each side of the equation to solve for r.
