Let R be the region bounded above by f(x) = 3 times the (sqr root of x) and the x-axis between x = 4 and x = 16. Approximate the area of R using a midpoint Riemann sum with n = 6 subintervals. Sketch a graph of R and illustrate how you are approximating it’ area with rectangles. Round your answer to three decimal places.
