    Find the surface area of a sphere whose diameter is equal to 24 cm.
    Question

    Find the surface area of a sphere whose diameter is equal to 24 cm.

    A.

    839π cm²

    B.

    841π cm²

    C.

    1161π cm²

    D.

    576π cm²

    Correct option is D

    Given:

    Diameter of the sphere = 24 cm

    Formula Used:

    Radius (r) = Diameter / 2
    Surface area = 4πr²

    Solution:

    The radius of the sphere is:
    r = 24 / 2 = 12 cm
    The surface area of the sphere is:
    Surface Area = 4πr²
    Substituting r = 12 cm:
    Surface Area = 4π(12)² = 4π × 144 = 576π
