Answer:
Area of 23958
Step-by-step explanation:
The Riemann sum is just the divide of a area into smaller areas and computing the sum of those areas. It is basically the integral of a function over an interval.
[tex]\int\limits {1089-x^2} \, dx[/tex]
over the interval [0,33].
[tex]\int\limits {1089-x^2} \, dx=1089x-(x^3)/3[/tex]
evaluate
[tex]=0-1089\cdot{33}-(33^3)/3=35937-11979=23958[/tex]
