Solve<br> -21 = -9 + 2/3b

Svet_ta [14]

Final Answer: $b = -18$

Steps/Reasons/Explanation:

Question: Solve $-21 = -9 + \frac{2}{3}b$ .

<u>Step 1</u>: Simplify $\frac{2}{3}b$ to $\frac{2b}{3}$ .

$-21 = -9 + \frac{2b}{3}$

<u>Step 2</u>: Regroup terms.

$-21 = \frac{2b}{3} - 9$

<u>Step 3</u>: Add $9$ to both sides.

$-21 + 9 = \frac{2b}{3}$

<u>Step 4</u>: Simplify $-21 + 9$ to $-12$ .

$-12 = \frac{2b}{3}$

<u>Step 5</u>: Multiply both sides by $3$ .

$-12$ × $3 = 2b$

<u>Step 6</u>: Simplify $-12$ × $3$ to $-36$ .

$-36 = 2b$

<u>Step 7</u>: Divide both sides by $2$ .

$-\frac{36}{2} = b$

<u>Step 8</u>: Simplify $-\frac{36}{2}$ to $-18$ .

$-18 = b$

<u>Step 9</u>: Switch sides.

$b = -18$

Answer:

Volume = 200.96 cubic feet

Step-by-step explanation:

Volume of a cone is given by the formula $V=\frac{1}{3}\pi r^2 h$

Where r is the radius and h is the height

Given r = 4 and height is 3 times that. So height is 4*3 = 12

Plugging these into the formula we get:

Volume of Cone = $\frac{1}{3}\pi (4)^2 (12)\\=\frac{1}{3}(3.14)(16)(12)\\=200.96$

Thus, Volume = 200.96 cubic feet
