    Answer:

    6.65*10^{27}W

    Explanation:

    The relationship of intensity:

    I=\frac{P}{4\pi r^{2} }

    Intensity: I=14W/m^{2}

    radius: r=6.00*10^{12} m

    Power is unknown

    Now we can apply the formula

    I=\frac{P}{4\pi r^{2} }\\P=I(4\pi r^{2})\\P=14.7(4*\pi *(6.00*10^{12} )^{2} )\\P=6.65*10^{27} W
