    The answer to your question is radius = 27.1 ft

    Step-by-step explanation:

    Data

    Surface area = 9244 ft²

    radius = ?

    Process

    To solve this problem, look for the formula of surface area, substitute values and simplify.

    1. - Formula of the area of a sphere

    Surface area = 4π r²

    2. - Solve for r²

    r² = Surface area / 4π

    3. - Substitution

    r² = 9244 / 4 (3.14)

    4. - Simplification

    r² = 9244/12.56

    r² = 735.98

    5. - Result

    r = 27.1 ft
