Answer:

180 inches

Step-by-step explanation:

The volume of a rectangular prism is length x width x height. So you would do (12)x(5)x(3) which would get you 180 inches.

Find the volume V obtained by rotating the region bounded by the curves about the given axis.

BartSMP [9]

Using the disk method, the volume is given by the integral

$\displaystyle \pi \int_{\pi/2}^\pi (9\sin(x))^2\,\mathrm dx = 81\pi \int_{\pi/2}^\pi \sin^2(x)\,\mathrm dx$

That is, each disk has a radius of y = 9 sin(x) and hence area = π (9 sin(x))². Add up infinitely many such disks by integrating. Then the volume is

$\displaystyle 81\pi \int_{\pi/2}^\pi \sin^2(x)\,\mathrm dx = \frac{81\pi}2 \int_{\pi/2}^\pi (1-\cos(2x))\,\mathrm dx \\\\ =\frac{81\pi}2 \left(x-\frac{\sin(2x)}2\right)\bigg|_{\pi/2}^\pi \\\\ = \frac{81\pi}2 \left( \left(\pi-\frac{\sin(2\pi)}2\right) - \left(\frac\pi2 - \frac{\sin(\pi)}2\right) \right) \\\\ = \boxed{\frac{81\pi^2}4}$

What is the result of 4 divided by 8/12

horrorfan [7]

Answer:

Step-by-step explanation:

4 ÷ 8/12

Change the sign to multiplication by switching the denominator with the numerator

=4 x 12/8

8 is divisible by 4 which gives you 2 therefore;

= 12/2

= 6

Hope this helps :)

The cylinder below has a volume of 536.94 cubic inches. What is the radius of the cylinder? (Use 3.14 for π.)

Anestetic [448]

We have been given volume of the cylinder which is 536.94 cubic inches. Now question says to find the radius of the cylinder.

Then we need to use formula of volume of cylinder which is given by :

$Volume = \pi r^2 h$

We see that there are three unknown values in the formula: {volume, radius-r, height-h}

So to find any one of them we must know other two values.

Volume is given but height is missing. So just for explanation i'm going to use height of the cylinder h= 19 inches

Now plug the value of volume and height in above formula

$536.94 = \pi r^2 *19$

$536.94 = 3.14 r^2 *19$

$536.94 = 59.66r^2$

$\frac{536.94}{59.66} =r^2$

$9=r^2$

take square root of both sides

3=r

Hence radius of the cylinder is 3 inches.

den301095 [7]

Answer:

6) B. q^18

7) C. 1/1296q^24

8) A. -12/5

Step-by-step explanation:

6. (q^9)^2

= q^(9*2)

= q^18

Answer

B. q^18

7.(6q^6)^-4

= 1/(6q^6)^4

= 1 / 1296q^24

Answer

C. 1/1296q^24

8. What is the value of 12x^-3 y^-1 for x = -1 and y = 5?

12x^-3 y^-1

= 12/x^3y

= 12 / (-1)^3 (5)

= 12/-5

= - 12/5

Answer

A. -12/5
