Given
we are given a function

over the interval [0,5].
Required
we need to find formula for Riemann sum and calculate area under the curve over [0,5].
Explanation
If we divide interval [a,b] into n equal intervals, then each subinterval has width

and the endpoints are given by

For k=0 and k=n, we get

Each rectangle has width and height as

we sum the areas of all rectangles then take the limit n tends to infinity to get area under the curve:

Here




Now Area=

So the required area is 66.6 sq units.
Answer:
56cm is not the answer for sure trust me
Step-by-step explanation:
I took the test so dont worry!
The radius of the shape is c. 3ft 3in
Answer:
16 is the awnser or at least I belive
The answer would be r= 9/2
