Volume of a cone = 1/3 π r² h 

235.5 = 1/3 (3.14) r² (9) 

(3.14) r² (9)  = 706.5

r² = 25

r = 5

Answer: Radius = 5 cm

Okay well since V=1/3 pi r^2 h you would replace the equation with 235.5=1/3 pi r^2 9. 706.5=pi r^2 9. 78.5=pi r^2. radius= square root 78.5 / pi

How to solve for literal equations with multiple variables
myrzilka [38]
<span>See examples for the method to solving literal equations for a given variable: Solve A = bh for b. Since h is multiplied times b, you must divide both sides by h in order to isolate b. Since (c+d) is divided by 2, you must first multiply both sides of the equation by 2</span>

Divide (-3x^2 - 9x) ÷ (x + 3) <br> please explain/show work! &lt;33
Stolb23 [73]

Step-by-step explanation:

<em>( - 3 {x}^{2} - 9x) \div (x + 3)</em>

<em>This </em><em>is </em><em>the</em><em> </em><em>original </em><em>equation</em><em> </em><em>so</em><em> </em><em>you </em><em>will</em><em> </em><em>open</em><em> </em><em>the</em><em> </em><em>brackets</em><em>.</em>

<em>- 3 {x}^{2}  - 9x \div x + 3</em>

<em>The</em><em> </em><em>x</em><em> </em><em>will</em><em> </em><em>cross</em><em> </em><em>the</em><em> </em><em>division </em><em>sign</em><em> </em><em>making</em><em> </em><em>it</em><em> </em><em>times</em><em> </em><em>x</em><em>.</em>

<em>3 {x}^{2}  - 9x \times x = 3</em>

<em>So</em><em> </em><em>you </em><em>will</em><em> </em><em>proceed</em><em> </em><em>to</em><em> </em><em>multiply</em><em> </em><em>the</em><em> </em><em>9</em><em>x</em><em> </em><em>by</em><em> </em><em>x</em><em> </em><em>making </em><em>it</em><em>;</em>

<em>3 {x}^{2}  - 9 {x}^{2} = 3</em>

<em>So</em><em> </em><em>you</em><em> </em><em>will</em><em> </em><em>subtract</em><em> </em><em>9</em><em>x</em><em>²</em><em> </em><em>from</em><em> </em><em>3</em><em>x</em><em>²</em><em> </em><em>which</em><em> </em><em>won't </em><em>be</em><em> </em><em>possible </em><em>so</em><em> </em><em>it </em><em>will</em><em> </em><em>be</em><em> </em><em>negative</em><em>.</em>

<em>- 6 {x}^{2} = 3</em>

<em>Then</em><em> </em><em>you </em><em>will</em><em> </em><em>square</em><em> </em><em>root</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>making</em><em> </em><em>it</em><em>;</em>

<em>- \sqrt{6 {x}^{2} } =  \sqrt{3}</em>

<em>So</em><em> </em><em>the</em><em> </em><em>²</em><em> </em><em>will</em><em> </em><em>cancel</em><em> </em><em>the</em><em> </em><em>√</em><em> </em><em>leaving </em>

<em>-6x</em><em>=</em><em>√</em><em>3</em>

<em>-6x</em><em>=</em><em>1</em><em>.</em><em>7</em><em>3</em><em>(</em><em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em>6</em><em>)</em>

<em>x</em><em>=</em><em>0</em><em>.</em><em>2</em><em>8</em><em>8</em>

<em>That</em><em>'s</em><em> </em><em>the</em><em> </em><em>final </em><em>answer</em><em>.</em>

Refer to the figure. Barton Road and Olive Tree Lane
Fantom [35]

Angles at right-angle add up to 90 degrees

The measure of acute angle Tryon Street forms with Barton Road is <em>33 degrees</em>

The angle is given as:

\mathbf{A = 57^o} ---- <em>Angle formed by Tryon Street with Olive Tree Lane. </em>

The measure of the acute angle formed by Tryon Street with Barton Road (B) is calculated using:

\mathbf{A + B = 90} ---- angle at right-angle

Make B the subject

\mathbf{B = 90 - A}

Substitute 57 for A

\mathbf{B = 90 - 57}

\mathbf{B = 33}

Hence, the measure of acute angle is 33 degrees
