<h2>●=> <u>Correct option</u> :</h2>

$\color{plum}\tt\bold{ A = 1.69 \pi \: mm²}$

<h3>●=> <u>Steps to derive correct answer</u> :</h3>

Given :

Circumference of a circle = 2.6π mm

We know that :

$\color{hotpink}\tt \: circumference \: of \: a \: circle\color{plum} = 2\pi r$

Which means :

$=\tt 2 \times r \times \pi = 2.6\pi$

$=\tt r\pi = \frac{2.6}{2}$

$=\tt r \pi = 1.3 \: mm$

Thus, the radius of this circle = 1.3 mm

The area of this circle :

$=\tt \pi {r}^{2}$

$=\tt 1.3 \times 1.3 \times \pi$

$\color{plum} = \tt1.69\pi$

Thus, the area of this circle = 1.69π

▪︎Therefore, the correct option is ○ A = 1.69π mm²

Need help and will be giving Brainliest

Katena32 [7]

Answer:

x-intercept (s):

For this case h (x) = 0

x2 - 2x - 8 = 0

(x-4) * (x + 2) = 0

x1 = 4

x2 = -2

y-intercept:

For this case x = 0

h (0) = (0)2 - 2 (0) - 8

h (0) = - 8

vertex:

We derive the equation:

h '(x) = x2 - 2x - 8

h (x) = 2x - 2

We match zero:

2x-2 = 0

x = 2/2

x = 1

We evaluate the function for x = 1

h (1) = (1)2 - 2 (1) - 8

h (1) = 1 - 2 - 8

h (1) = -9

The vertex is:

(1, -9)

axis of symmetry of the function:

x = 1

A sofa is on sale for $703 which is 24% less than the regular price what is the regular price

Firdavs [7]

Hello!

We could write this as an equation below.

0.76x=703

We divide both sides by 0.76.

x=925

Therefore, the regular price is $925.

I hope this helps!

3. Complete the proof below.<br><br><br> Help please!!!

baherus [9]

Answer:

The completed proof is presented as follows;

The two column proof is presented as follows;

Statements ${}$ Reason

1. $\overline {HI}$ ║ $\overline {KL}$ , J is the midpoint of $\overline {HL}$ ${}$ 1. Given

2. ∠IHJ ≅ ∠JLK ${}$ 2. Alternate angles are congruent

3. ∠IJH ≅ ∠KJL ${}$ 3. Vertically opposite angles

4. $\overline {HJ}$ ≅ $\overline {JL}$ ${}$ 4. Definition of midpoint

5. ΔHIJ ≅ ΔLKJ ${}$ 5. By ASA rule of congruency

Step-by-step explanation:

Alternate angles formed by the crossing of the two parallel lines $\overline {HI}$ and $\overline {KL}$ , by the transversal $\overline {HL}$ are equal

Vertically opposite angles formed by the crossing of two straight lines $\overline {IK}$ and $\overline {HL}$ are always equal

A midpoint divides a line into two equal halves

Angle-Side-Angle, ASA rule of congruency states that two triangles ΔHIJ and ΔLKJ, that have two congruent angles, ∠IHJ in ΔHIJ ≅ ∠JLK ${}$ in ΔLKJ and ∠IJH in ΔHIJ ≅ ∠KJL in ΔLKJ, and that the included sides between the two congruent angles is also congruent $\overline {HJ}$ ≅ $\overline {JL}$ , then the two triangles are congruent, ΔHIJ ≅ ΔLKJ.
