    circle


    Col A: a+d
    Col B: b+c the choices


    COL A is greater
    col b is greater
    both are equal
    can not be determined

    i did like since both were radius i equated both like a^2+c^2=b^2+d^2
    a^2-d^2=b^2-c^2
    (a+d)(a-d)=(b+c)(b-c).then i was stuck can any one help me out of this
