List x1, x2, x3, x4 where xi is the right endpoint of the four equal intervals used to estimate the area under the curve of f(x)

anzhelika [568]

From x=a to x=b, with n subintervls, the width between each is (b-a)/n

so from x=3 to x=5 and 4 intervales is (5-3)/4=2/4=1/2

increments of 1/2 each time
we need 4 of them

I see that xi is the right endpoint so I would guess that we take the right Riemann sum
so we start at 3+0.5 or 3.5

so 3.5, 4,4.5,5

C I would say

Find the area of the circle to the nearest whole number, if necessary!

astra-53 [7]

Answer:

The circle has an area of about 1385 square mm.

Step-by-step explanation:

Let's recall that circles have an area that can be found with the following formula:

$A=\pi r^{2}$

where r is the radius of the circle.

Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.

$A=\pi (21)^2\\A=441\pi \\A=1385.44236...$

So, to the nearest whole number, the area of the circle is 1385 square mm.
