    Answer: 254.3 inches²

    Step-by-step explanation:

    The shape of a soccer ball is a sphere. The formula for calculating surface area of a sphere = 4πr²

    Since diameter = 9 inches

    Radius = Diameter/2 = 9/2

    Radius = 4.5 inches

    π = 3.14

    Surface area = 4πr²

    = 4 * 3.14 * 4.5²

    = 4 * 3.14 * 4.5 * 4.5

    = 254.3 inches²
