Answer:

C. $24\pi$ inches.

Step-by-step explanation:

We are given that,

The radius of the circle = 12 inches

Since, the circumference of a circle = $2\pi r$ , where r= radius.

Substituting r = 2 in the formula, we get,

Circumference of a circle = $2\pi \times 12= 24\pi$ inches

<h3>Hence, the circumference of the circle is $24\pi$ inches.</h3>

So, option C is correct.

Answer:

1.x^2

2.x+8

3.x

Step-by-step explanation:

Length of old is x inches.

Because it is square we have that area of the old canvas : $x^2$

When we read : width of new is increased by 8 so : x+8

Length is x.

The difference of areas:

Old canvas : A1= $x^2$

New canvas : $A2=x(x+8)=x^2+8x$

Now we can find A2-A1:

$x^2+8x-x^2=8x$

solong [7]

Answer:

83.4% or 83%

Step-by-step explanation:

when trying to find a percent, divide the numerator (# of correct answers) by the denominator (# of total questions possible to get correct)

Which would be 16.67 divided by 20 which equals .8335. Move the decimal point over two placements which would be 83.35. I rounded it up to 83.4. If trying to find a whole number not a decimal it would be 84%. Depending on the grading scale, it would be a B.
