C) Find the radius of the original circular track whose circumference is 88cm. Calculate the circumference of the new circular track whose area is 9 times the area
of the original circular track.

​

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
