    108°

    Step-by-step explanation:

    The formula for the Area of a sector when the central angle is in degrees = (θ/360°) * πr²

    Formula for central angle in degrees is derived as:

    θ = (Area of a sector * 360°) : πr²

    From the question, we are given

    Area of the sector = 30π cm²

    Radius = 10 cm

    Hence, we have

    θ = (30π * 360°) : π * 10²

    θ = 108°

    Therefore, the central angle in degrees is 108°
