\boxed{r=\frac{S}{2\pi h}}

<h2>Explanation:</h2>

Remember you have two write complete questions in order to get good and exact answers. Here I'll assume you want to isolate the radius (r). So:

The formula for the lateral surface area of a cylinder is:

S=2\pi rh \\ \\ \\ Where: \\ \\ S:Lateral \ surface \ area: \\ \\ r:Radius \\ \\ h:Height[tex][tex]Dividing \ both \ sides \ by \ 2\pi h: \\ \\ S=2\pi rh \\ \\ \frac{S}{2\pi h}=\frac{2\pi rh}{2\pi h} \\ \\ \\ Finally: \\ \\ \boxed{r=\frac{S}{2\pi h}}

There are several ways two triangles can be congruent.

  • \mathbf{AC = BD}<em> congruent by SAS</em>
  • \mathbf{\angle ABC \cong \angle BAD}<em> congruent by corresponding theorem</em>

In \mathbf{\triangle AOL} and \mathbf{\triangle BOK} (see attachment), we have the following observations

1.\ \mathbf{AO = DO} --- Because O is the midpoint of line segment AD

2.\ \mathbf{BO = CO} --- Because O is the midpoint of line segment BC

3.\ \mathbf{\angle AOB =\angle COD} ---- Because vertical angles are congruent

4.\ \mathbf{\angle AOC =\angle BOD} ---- Because vertical angles are congruent

Using the SAS (<em>side-angle-side</em>) postulate, we have:

\mathbf{AC = BD}

Using corresponding theorem,

\mathbf{\angle ABC \cong \angle BAD} ---- i.e. both triangles are congruent

The above congruence equation is true because:

  1. <em>2 sides of both triangles are congruent</em>
  2. <em>1 angle each of both triangles is equal</em>
  3. <em>Corresponding angles are equal</em>

which of the following is a point slope equation of a line with the point (-6,2) and a slope of 1/2?
wariber [46]

Answer:

y - 2 = 1/2(x + 6)

General Formulas and Concepts:

<u>Algebra I</u>

Point-Slope Form: y - y₁ = m(x - x₁)

  • x₁ - x coordinate
  • y₁ - y coordinate
  • m - slope<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (-6, 2)

Slope <em>m</em> = 1/2

<u>Step 2: Find</u>

  1. Substitute in variables [Point-Slope Form]:                                                     y - 2 = 1/2(x - -6)
  2. Simplify:                                                                                                             y - 2 = 1/2(x + 6)
