Answer:

(5 - 1)^2 + (1 - 1)^2 = 4^2

Step-by-step explanation:

Circle equation: ( x - h )^2 + ( y - k )^2 = r^2

(h,K) is the coordinate of the center.

Center: (1,1)

(x,y) choose a point that could be the radius. (I choose the one on the top left side).

Point: (5,1)

Diameter: 8

Radius: 4

Plug in:

( x - h )^2 + ( y - k )^2 = r^2

(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)

Solve to see if it's true,

(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)

4^2 + 0^2 = 4^2

16 = 16 (This is true, therefore, the equation is correct).

A) Use the method of cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the given cur
Leno4ka [110]

(a) See the attached sketch. Each shell will have a radius <em>y</em> chosen from the interval [2, 4], a height of <em>x</em> = 2/<em>y</em>, and thickness ∆<em>y</em>. For infinitely many shells, we have ∆<em>y</em> converging to 0, and each super-thin shell contributes an infinitesimal volume of

2<em>π</em> (radius)² (height) = 4<em>πy</em>

Then the volume of the solid is obtained by integrating over [2, 4]:

\displaystyle 4\pi \int_2^4 y\,\mathrm dy = 2\pi y^2\bigg|_{y=2}^{y=4} = 2\pi (4^2-2^2) = \boxed{24\pi}

(b) See the other attached sketch. (The text is a bit cluttered, but hopefully you'll understand what is drawn.) Each shell has a radius 9 - <em>x</em> (this is the distance between a given <em>x</em> value in the orange shaded region to the axis of revolution) and a height of 8 - <em>x</em> ³ (and this is the distance between the line <em>y</em> = 8 and the curve <em>y</em> = <em>x</em> ³). Then each shell has a volume of

2<em>π</em> (9 - <em>x</em>)² (8 - <em>x</em> ³) = 2<em>π</em> (648 - 144<em>x</em> + 8<em>x</em> ² - 81<em>x</em> ³ + 18<em>x</em> ⁴ - <em>x</em> ⁵)

so that the overall volume of the solid would be

\displaystyle 2\pi \int_0^2 (648-144x+8x^2-81x^3+18x^4-x^5)\,\mathrm dx = \boxed{\frac{24296\pi}{15}}

I leave the details of integrating to you.
