The volume of the cross-section perpendicular to the solid is the amount of space in the cross-section
<h3>How to set up the integral?</h3>
The question is incomplete;
So, I will give a general explanation on how to set up a definite integral for volume of a solid
Assume the solid is a cone;
Using the disk method, the integral of the volume is:

Using the washer method, the integral of the volume is:
![V = \int\limits^a_b {\pi [R(x)^2 -r(x)^2 ]} \, dx](https://tex.z-dn.net/?f=V%20%3D%20%5Cint%5Climits%5Ea_b%20%7B%5Cpi%20%5BR%28x%29%5E2%20-r%28x%29%5E2%20%5D%7D%20%5C%2C%20dx)

6 because in 9 years Travis will be 30 and divide that by 2 is 15. 15-9=6
Circumference of a circle = 2πr
C = 2π(4)
C = 8π
C = 8 * 3.14 = 25.12
In short, Your Answer would be 25.12
Hope this helps!
Hello!
To find the slope of the line that passes through the points (3, 6) and (5, 3), we will need to use the slope formula.
Slope formula is
.
Now, we should assign the given points as x1, y1 or x2, y2. The point (3, 6) can be assigned to x1, y1, and (5, 3) to x2, y2.
Now, substitute the given points into the slope formula.

Therefore, the slope of the line is choice A, -3/2.
This triangle has height 8 and base 4, so it's area is 4*8/2=16.
