Answer: The answers are equal and \pi r^2h.

Step-by-step explanation: We are given the steps with some missing words for the derivation of the volume of a cylinder. The figure shows a rectangular prism and a cylinder.

The complete steps are as follows:

The rectangular prism and the cylinder have <u>equal</u> heights.

The area of the base of the rectangular prism and every cross section parallel to its base is \pi r^2 .

The area of the base of the cylinder and every cross section parallel to its base is \pi r^2 .

By Cavalieri's principle, this rectangular prism and this cylinder have equal volumes.  

The volume of the rectangular prism is \pi r^2h.  

Therefore, the volume of the cylinder is \pi r^2h.

Thus, the steps are completed.

In ΔUVW, w = 3 inches, ∠W=23° and ∠U=73°. Find the length of u, to the nearest 10th of an inch.
kirza4 [7]

Answer:

<h2>7.4inches</h2>

Step-by-step explanation:

Check the attachment for the diagram. Sine rule will be used to get the unknown side of the triangle.

According to the rule;

\frac{u}{sinU} =  \frac{v}{sinV} = \frac{w}{sinW}\\\frac{u}{sinU} = \frac{w}{sinW}

Given w = 3 in, ∠W=23° and ∠U=73°, on substituting into the equation above to get u we have;

\frac{u}{sin73^{0} } = \frac{3}{sin23^{0} }\\usin23^{0} = 3sin73^{0}\\u = \frac{3sin73^{0} }{sin23^{0} }\\u = \frac{2.87}{0.39} \\u = 7.358\\u = 7.4in

The length of u is 7.4inches to nearest 10th of an inch

3x-7=4x+10 <br> show the steps pleeease
Fudgin [204]

Answer:

-17

Step-by-step explanation:

3x-7=4x+10

Add 7 to both sides & simplify

3x-7=4x+10

+7           +7

3x=4x+17

Subtract 4x from both sides & simplify

3x=4x+17

-4x  -4x

-x=17

*Negative x equals -1*

Divide both sides by -1 & simplify

\frac{-x}{-1} =\frac{-17}{-1}

x=-17
