        So I’ve looked up the radius of the moon, which is 1737.4 km. From there we can work this out.

        Let’s assume the moon is a perfect sphere. So volume =4/3 π r cubed.

        1737.4 cubed = 5,244,443,990 (huge!)

        Multiplied by π = 16,475,906,711

        Multiplied by 4/3 = 21,967,875,613

        To get 9%, we can divide it by 100 then multiply by 9 = 1,977,108,805 km^3

        I have rounded to the nearest whole number.
