Answer:
Step-by-step explanation:
For this case we have the following plot on the figure attached.
We know on this case that 
represent our radius for the square, since we need cross sections perpendicular to the y axis.
We find the intersection points like this:
Since we are assuming squares for the cross sections the area is given by 
where r = x= -2y+6.
Since our radius is on terms of x we can create a integral with limits on x in order to find the volume, And we can use the following integral in order to find the volume.
On the left part we are using the following property from algebra:
And after do the integral we got this:
Lets work backwards. π r2 = 62 cm. 62 / 3.14 = 17.75. Square root of 17.75 = 4.21. Okay, now using the radius of 4.21 we will use the formula C = 2 πr. C = 2 (3.14)(4.21) = 2 (13.22) = 26.44. So the circumference of each button is approximately 26.44 cm.

Answer:
Examine the given sequence. Which statement is not correct?
A) If c = 14, the relationship is linear and f(x) = 2x + 8 for x = {1, 2, 3, ...}.
B) If c = 14, the relationship is linear and an = 10 + 2(n − 1) for n = {1, 2, 3, ...}.
C) If c = 14.4, the relationship is exponential and f(x) = 10(1.2)(x − 1) for x = {1, 2, 3, ...}.
D) If c = 14.4, the relationship is exponential. a1 = 10 and an + 1 = an + 1.2 for n = {1, 2, 3, ...}.
