The base of a circular fence with radius 10 m is given by x = 10 cos(t), y = 10 sin(t). The height of the fence at position (x, y) is given by the function h(x, y) = 3 + 0.03(x² - y²), so the height varies from 0 m to 6 m. Suppose that 1 L of paint covers 100 m².
Determine how much paint you will need if you paint both sides of the fence. (Round your answer to two decimal places.)
