To get the answer we have to tranform into y=ax+b form
-2x+4y=68          /+2x
4y=2x+68          /:4
y=\frac{1}{2} x+17  - its the result

13x+4y=284           /-13x
4y=-13x+284        /:4
y=- \frac{13}{4}+ 71
y=-3 \frac{1}{4}x+71 - its the result

The lateral area of a cone is 19.2π in2. The radius is 2.4 in. Find the slant height.
Alexus [3.1K]

The slant height of a cone with lateral surface are of 19.2π inches squared and radius of 2.4 inches is 8 inches.

<h3>Lateral surface area of a cone</h3>

The formula for the lateral surface area of a cone is described as follows:

Lateral area = πrl

where

  • r = base radius
  • l = slant height

Therefore,

Lateral area = 19.2π inches²

r = 2.4 inches

Lateral area = π × 2.4 × l

19.2π = 2.4πl

divide both sides by 2.4π

l = 19.2π / 2.4π

l = 8 inches

Someone please help me
pentagon [3]

Answer:

Option 3 or Option 4.

Step-by-step explanation:

I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.

On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.

In case you only can answer with one, I'll say is option 3, hope it helps!
