Volume formula : length x width x height
Therefore, 24 x 10 x 16
=3840 in3

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line. Y = (4/9) x
frez [133]

Answer:

V = 8.06 cubed units

Step-by-step explanation:

You have the following curves:

y_1=\frac{4}{9}x^2=f(x)\\\\y_2=\frac{13}{9}-x^2=g(x)

In order to calculate the solid of revolution bounded by the previous curves and the x axis, you use the following formula:

V=\pi \int_a^b [(g(x))^2-(f(x))^2]dx       (1)

To determine the limits of the integral you equal both curves f=g and solve for x:

f(x)=g(x)\\\\\frac{4}{9}x^2=\frac{13}{9}-x^2\\\\\frac{4}{9}x^2+x^2=\frac{13}{9}\\\\\frac{13}{9}x^2=\frac{13}{9}\\\\x=\pm 1

Then, the limits are a = -1 and b = 1

You replace f(x), g(x), a and b in the equation (1):

V=\pi \int_{-1}^{1}[(\frac{13}{9}-x^2)^2-(\frac{4}{9}x^2)^2]dx\\\\V=\pi \int_{-1}^1[\frac{169}{81}-\frac{26}{9}x^2+x^4-\frac{16}{81}x^4]dx\\\\V=\pi \int_{-1}^1 [\frac{169}{81}-\frac{26}{9}x^2+\frac{65}{81}x^4]dx\\\\V=\pi [\frac{169}{81}x-\frac{26}{27}x^3+\frac{65}{405}x^5]_{-1}^1\\\\V\approx8.06\ cubed\ units

The volume of the solid of revolution is approximately 8.06 cubed units

Which equation represents a circle that contains the point (–5, –3) and has a center at (–2, 1)?
melisa1 [442]

Answer:

(x + 2)² + (y - 1)² = 25

Step-by-step explanation:

radius: r² = (1 - (-3))² + (-2 - (-5))² = 16 + 9 = 25

r = 5

Circle: (x - h)² + (y - k)² = r²

center: (-2 , 1)      h = -2       k = 1

(x + 2)² + (y - 1)² = 25
