    Answer:144π

    Step-by-step explanation:

    C=2 x π x r

    24π=2πr

    Divide both sides by 2π we get

    24π/2π=2πr/2π

    12=r

    radius(r)=12cm

    When radius(r) is multiplied by 6 we get new radius(r) of 12×6=72cm

    c=2xπxr

    New circle circumference will be:

    c=2xπx72

    c=144π or 144pi
