    First, convert the radius of the sphere from centimeter to meter.

    r = (2.7 cm) (1 m / 100 cm)

    r = 0.027 m

    Then, calculate for the surface area of the given by the equation,

    A = 4πr²

    Substituting the known values,

    A = 4 (π) (0.027 m) ²

    A = 9.16 x 10⁻³ m²

    Then, multiply the calculated area to the charge density given to determine the total charge.

    C = (6.9 x 10⁻⁶ C/m²) (9.16 x 10⁻³ m²)

    C = 6.32 x10⁻⁸ C

    Answer: C = 6.32 x 10⁻⁸ C
