    Circumerence=2 times pi times radius

    circumference=62.8

    62.8=2 times pi times r

    divide both sides by 2

    31.4=pir

    aprox pi to 3.14 and divide both sides by 3.14

    10=r

    radius = 10in

    Formula for circumference is c = 2 (pi) r

    62.8 = 2 (3.14) r

    62.8 = 6.28 (r)

    62.8/6.28 = r

    10 = r

    Radius is 10 inches
