    88cm=2 (22/7) r

    88=6.29r

    r=13.99 or 14

    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.
