To find the volume of a cylinder, multiply the area of its bottom (a circle with area ar?) by its height, h. The top and bottom of a cylinder are equal-sized circles. A cylindrical water tower has a radius of 21 feet and a height of 15 feet

What expression converts 100 inches per minute to feet per minute?
ehidna [41]

1 foot= 12 inches.

To convert you must have "2 fractions" to multiply.

Your first fraction must be 100in/1min. (100 inches per 1 minute).

The second should serve to convert inches to feet. It should be 1 foot/ 12 inches. (1 foot per 12 inches).

Your product should be 100ft/12 which equals 8.3 repeating or 25/3 (8 1/3) feet.

Find the volume of the solid under the plane 3x+2y−z=0 and above the region enclosed by the parabolas y=x^2 and x=y^2.
Yuri [45]

The region in the <em>x</em>-<em>y</em> plane is the set of points

R=\{(x,y)\mid0\le x\le 1,x^2\le y\le\sqrt x\}

The height of the solid falls between the <em>x</em>-<em>y</em> plane (for which <em>z</em> = 0) and the equation of the plane, <em>z</em> = 3<em>x</em> + 2<em>y</em>.

So the volume is

\displaystyle\int_0^1\int_{x^2}^{\sqrt x}\int_0^{3x+2y}\mathrm dz\,\mathrm dy\,\mathrm dx

=\displaystyle\int_0^1\int_{x^2}^{\sqrt x}(3x+2y)\mathrm dy\,\mathrm dx

=\displaystyle\int_0^1(3x^{3/2}+x-3x^3-x^4)\,\mathrm dx

=\displaystyle\frac65+\frac12-\frac34-\frac15=\boxed{\dfrac34}

Which is the right one. i need help!!!!
Svetlanka [38]

Answer: 23

step by step:

The angle is 90 degrees

(2x+14) + (x+7) = 90

(2x+ x) + (14+7) = 90

3x+21 = 90 (subtract 21 from both sides)

3x+ 21 - 21 = 90 - 21

3x = 69 ( divide each side by 3)

x = 23
