(a) Use Trapezoid rule with n=4, TRAP(4), to estimate the area of the rink. Is this an
overestimation or underestimation?
(b) Suppose the bounding curve is given by a function
Y 100
64
Express the area of the rink as a definite integral.
(c) Find the exact area of the rink. Round your answer to two decimal places.
