$2(7x-5)-6x+2=0\\\\\implies 14x -10 -6x +2=0\\\\\implies 8x -8 =0\\\\\implies 8(x-1) =0\\\\\implies x -1 =0\\\\\implies x =1$

D . 18 units

Step-by-step explanation:

We know that the circumference of the circle is given by :-

$C=2\pi r$ , where r is the radius of the circle.

Given : The radius of the circle = 3 units

Then , the circumference of the circle will be :-

$C=2\pi (3)$

We know the the value of $\pi =3.14$ , we estimate the value of $\pi =3$

C=2(3) (3)=18

Hence, the the best estimate of the circumference of this circle is 18 units.
