Find an approximation of the area of the region r under the graph of the function f on the interval [1, 3]. use n = 4 subintervals. choose the representative points to be the right endpoints of the subintervals. f(x) = 7/x

The area of the region is an illustration of definite integrals.

The approximation of the area of the region R is 9.98

The given parameters are:

------ sub intervals

Using 4 sub intervals, we have the partitions to be:

List out the right endpoints

Calculate f(x) at these partitions

So, the approximated value of the definite integral is:

This becomes

Expand

Hence, the approximation of the area of the region R is 9.98

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
