8. For circle A, the circumference is 31.4 ft. What is the area? Use 3.14 for pi
telo118 [61]

Answer:

\huge\boxed{\sf A = 78.5\ ft\²}

Step-by-step explanation:

Circumference = C = 31.4 ft

We know that,

<h3>C = 2πr</h3>

Where, r is the radius

31.4 = 2(3.14)r

31.4 = 6.28(r)

Divide 6.28 to both sides

31.4/6.28 = r

5 ft. = r

<h3>r = 5 ft.</h3>

Now,

<h3><u>Finding area:</u></h3>

A = πr²

A = (3.14)(5)²

A = (3.14)(25)

<h3>A = 78.5 ft²</h3>

\rule[225]{225}{2}

What is (12-2i) (5+3i) multiplied?
Ilya [14]
= 12*5 + 12*3i - 5*2i - 6i^2    (remember that i^2 = -1) so:-

= 60 +26i - 6*(-1)

= 60 + 26i + 6

= 66 + 26i

What is the image of (-4,-2) after a reflecton over the line y= -x
Slav-nsk [51]

The image of (-4, -2) after a reflection over the line y = -x is (2, -4).

<h3>What is a transformation?</h3>

In Mathematics, a transformation can be defined as the movement of a point from its original (initial) position to a final (new) location. This ultimately implies that, when an object is transformed, all of its points would be transformed as well.

<h3>The types of transformation.</h3>

Generally, there are different types of transformation and these include the following:

  1. Reflection
  2. Rotation
  3. Translation
  4. Dilation

<h3>What is a reflection?</h3>

A reflection can be defined as a type of transformation which moves every point of the object by producing a flipped but mirror image of the geometric figure.

In Geometry, a reflection over the y-axis is given by this rule (x, y) → (-x, y). Thus, line y = -x would become:

(-4, 2) → (2, -4).
