A block of ice is in the shape of a square prism. You want to put the block of ice in a cylindrical cooler. The equation s² = 2r² represents the minimum radius r needed for the block of ice with side length s to fit in the cooler.
a. Solve the equation for r.
b. Use the equation in part (a) to find the minimum radius needed when the side length of the block of ice is √98 inches.
