Given graph of a function with rectangles representing a Riemann sum, find the total area.

Question: The rectangles in the graph below illustrate a left endpoint Riemann sum for f(x) = 3sin x on the interval [0, π]. The value of this Riemann sum is (?).
a) The rectangles in the graph below illustrate a left endpoint Riemann sum for f(x) = 3sin x on the interval [0, π]. The value of this Riemann sum is (?).

Left endpoint Riemann sum for y = 3sin x on [0, π]

b) The rectangles in the graph below illustrate a right endpoint Riemann sum for f(x) = 3sin x on the interval [0, π]. The value of this Riemann sum is (?).

Right endpoint Riemann sum for y = 3sin x on [0, π]
