Answer:

6.4 units (nearest tenth)

Step-by-step explanation:

Distance between 2 points

$= \sqrt{(y1 - y2)^{2} + (x1 - x2)^{2} }$

Distance between A and B

$= \sqrt{[ - 1 - ( - 5)]^{2} + ( - 1 - 4)^{2} }$

$= \sqrt{( - 1 + 5)^{2} + ( - 1 - 4) {}^{2} }$

$= \sqrt{ {4}^{2} + ( - 5) {}^{2} }$

$= \sqrt{41}$

= 6.4 units (nearest tenth)

Find the volume of the solid formed by rotating the region bounded by the given curves about the indicated axis. Y = 1x, y = 1,

Goryan [66]

The disk method will only involve a single integral. I've attached a sketch of the bounded region (in red) and one such disk made by revolving it around the y-axis.

Such a disk has radius x = 1/y and height/thickness ∆y, so that the volume of one such disk is

π (radius) (height) = π (1/y)² ∆y = π/y² ∆y

and the volume of a stack of n such disks is

$\displaystyle V_n = \sum_{i=1}^n \pi {y_i}^2 \Delta y$

where $y_i$ is a point sampled from the interval [1, 5].

As we refine the solid by adding increasingly more, increasingly thinner disks, so that ∆y converges to 0, the sum converges to a definite integral that gives the exact volume V,

$\displaystyle V = \lim_{n\to\infty} V_n = \int_1^5 \frac{\pi}{y^2} \, dy$
