C=2πr,when c=88cm.use 22/7 for π. show the work

If we are then solving for radius what you will begin with ( plug in 88cm for C in the formula, divide both sides by 2, multiply both sides by the recipricol of 22/7 which will be 7/22 and on one side u will be left with r and it will equal 14. so ur radius is 14.

Quadrant i is the point
