Find the volume of the solid generated when R​ (shaded region) is revolved about the given line. x=6−3sec y​, x=6​, y= π 3​, and
Dmitrij [34]

Answer:

V=9\pi\sqrt{3}

Step-by-step explanation:

In order to solve this problem we must start by graphing the given function and finding the differential area we will use to set our integral up. (See attached picture).

The formula we will use for this problem is the following:

V=\int\limits^b_a {\pi r^{2}} \, dy

where:

r=6-(6-3 sec(y))

r=3 sec(y)

a=0

b=\frac{\pi}{3}

so the volume becomes:

V=\int\limits^\frac{\pi}{3}_0 {\pi (3 sec(y))^{2}} \, dy

This can be simplified to:

V=\int\limits^\frac{\pi}{3}_0 {9\pi sec^{2}(y)} \, dy

and the integral can be rewritten like this:

V=9\pi\int\limits^\frac{\pi}{3}_0 {sec^{2}(y)} \, dy

which is a standard integral so we solve it to:

V=9\pi[tan y]\limits^\frac{\pi}{3}_0

so we get:

V=9\pi[tan \frac{\pi}{3} - tan 0]

which yields:

V=9\pi\sqrt{3}]

Yes or no 2 problems below giving brainlest
astra-53 [7]

Answer:

Problem 13: yes

Problem 14: no

Step-by-step explanation:

Problem 13:

Plug the values of x and y to solve.

-23 = -7(5) + 12

-23 = -35 + 12

-23 = -23

The values are equal, so the coordinates <u>do</u> solve the equation. It's a yes.

-----------------------------------------------------------------------

Problem 14:

Plug the values of x and y to solve.

-9 = -7(-3) + 12

-9 = 21 + 12

-9 = 33

The values are not equal, so the coordinates <u>do not</u> solve the equation. It's a no.

hope this helps :)
