Answer:

3.1 m

Step-by-step explanation:

Okay, to find the circumference of a circle the formula is c = 2 3.14 x r.

R represents the radius.

So, you are trying to find the radius of a circle not the circumference of a circle. We know what the circumference is (19.468).

Therfore you would multiply each answer choice by 2 then by 3.14.

3.1 x 2 = 6.2

6.2 x 3.14 = 19.468

19.468 = 19.468

So your answer is 3.1 m.

To double check all your math you would do this to each answer choice.

I hope that this helped! :)

Answer:

17.7

Step-by-step explanation:

This figure is a pentagon - a shape with 5 sides. In a pentagon, the figure's angles add to 540.

100 + 7x-4 + 3x + 23 + 9x - 6 + 90 = 540

190 +19x + 13 = 540

203 + 19x = 540

19x = 337

x = 17.7

Answer:

<h2>The x-interecepts are 5.6 and -1.4, approximately.</h2>

Step-by-step explanation:

The given equation is

$5x^{2} -21x=39$

Where $a=5$ , $b=-21$ and $c=39$ , let's use the quadratic formula

$x_{1,2}=\frac{-b(+-)\sqrt{b^{2}-4ac } }{2a} =\frac{-(-21) (+-)\sqrt{(-21)^{2} -4(5)(-39)} }{2(5)}\\ x_{1,2}=\frac{21(+-)\sqrt{441+780} }{10}=\frac{21(+-35)}{10}\\x_{1}=\frac{21+35}{10}=\frac{56}{10} \approx 5.6\\ x_{2}=\frac{21-35}{10}=\frac{-14}{10} \approx -1.4$

Therefore, the x-interecepts are 5.6 and -1.4, approximately.
