Find the volume of the solid of revolution formed by rotating about the x--axis the region bounded by the given curves.

Maslowich

Answer:

16 pi cubic units

Step-by-step explanation:

Given that a region is bounded by

$f(x)=√x, y=0, x=1, x=4$

And the region is rotated about x axis.

We can find that here radius would be y value and height would be dx

So volume would be as follows:

If f(x) is rotated about x axis volume

= $\pi \int\limits^b_a {y^2} \, dx \\=\pi \int\limits^4_1 {x} \, dx\\=\pi *x^2 ^4_1\\= \pi*16-1\\=15\pi$

cubic units.

The value of y varies directly with x and y=12 when x=-6 find y when x=-4

FinnZ [79.3K]

Answer:

B)8

Step-by-step explanation:

That is the right answer because when y=12, x=-6

12/-6 = -2

This means that x = y/-2

or y = x * -2

-4 * -2 = 8
