    The ratio of area of larger circle to area of smaller circle is 4:1

    Step-by-step explanation:

    Area of circle A=πr², d (diameter) = 2r (radius)

    Area of larger circle = πR²

    Area of smaller circle = πr²

    Diameter of larger circle = 2 diameter of smaller circle

    D = 2 d

    2R = 2*2r

    2R = 4r divide by 2

    R = 2r

    Area of larger circle = πR²=π (2r) ² = π*4r²

    Area of smaller circle = πr²

    π*4r² / πr² = 4/1

    see below

    Step-by-step explanation:

    Smaller circle

    radius = r

    A = pi r^2

    Larger circle

    radius = 2r

    A = pi (2r) ^2 = 4pi r^2

    larger area / smaller area

    4 pi r^2 / pi r^2

    4/1
