    Answer:

    r=\sqrt{\frac{682}{4\pi}}\ m

    Step-by-step explanation:

    we know that

    The surface area of a sphere is equal to

    SA=4\pi r^{2}

    we have

    SA=682\ m^{2}

    substitute and solve for r

    682=4\pi r^{2}

    r^{2}=\frac{682}{4\pi} \\ \\r=\sqrt{\frac{682}{4\pi}}\ m
