    the cross-sectional area is 58.63 m²

    Step-by-step explanation:

    the cross-section of a cylinder perpendicular to its length is a circle whose radius is the cylinder's radius. Thus the corresponding area A is

    A = π*R² = π * (4.32 m) ² = 58.63 m²

    therefore the cross-sectional area is 58.63 m²

    CSA = 58.63 m^2

    Therefore, the cross-sectional area perpendicular to its length is 58.63 m^2

    Step-by-step explanation:

    The cross sectional area of a cylinder that is perpendicular (that means at angle 90°) to the length of the cylinder is the area of the circular top of the cylinder when viewing the cylinder from the top. It can be expressed mathematically as;

    CSA = πr^2 ... 1

    Where r is the radius of the cylinder.

    Given;

    radius r = 4.32 m

    length l = 9.00 m

    Substituting the value of r into equation 1;

    CSA = π * (4.32) ^2

    CSA = 58.63 m^2

    Therefore, the cross-sectional area perpendicular to its length is 58.63 m^2
