    Find circumference

    C=2pir

    c=2pi10

    c=20pi

    circle is 360 degrees

    12pi/20pi=x/360

    6/10=x/360

    3/5=x/360

    216=x

    answer si 216 degrees

    if yo want radians

    3/5 was the fraction and 2pi is total so

    3/5 times 2pi=6pi/5 radians

    216 degrees or 6pi/5 radians
