Answer:

Step-by-step explanation:

d = c/pi

so d = 62.8/pi

d = 62.8/pi or appr 19.99in

r = d/2

so r = 62.8/2pi or 31.4/pi appr 19.99/2

$a = \pi r^{2}$

$a = \pi *(31.4/\pi)^2$

then

$a = 985.96/pi$

a = approximately 313.84

answer is rowan

Answer:

B. $x^{2} +2x-8$

Step-by-step explanation:

Here the best method to solve is by substituting the end values of the set in each option , otherwise it will a time consuming problem.

Now substitute x=-4 in all the options

A. $x^{2} -2x-8$

16+8-8=16>0

so out of option A and C option C is correct.

B. $x^{2} +2x-8$

16-8-8=0 which means for the values of x>-4 $x^{2} +2x-8$ is less than 0

Now substitute x=2 in all the options

A. $x^{2} -2x-8$

4-4-8=-8<0 . so option A and C both are incorrect.

B. $x^{2} +2x-8$

4+4-8=0 which means for the values of x<2 $x^{2} +2x-8$ is less than 0

Therefore the correct option is B

Answer:

5) A

6) A

Step-by-step explanation:

5) With the sides of the rectangle being dilated, multiply the side lengths by the scale factor

7.5(2.2) and 3(2.2)

16.5 and 6.6

6) Multiply the coordinates by the scale factor as dilations work as (x, y) -> (kx, ky)
