    20π square units

    Step-by-step explanation:

    The area of a sector is given by ...

    A = (1/2) r²θ

    where r is the radius and θ is the central angle in radians.

    Filling in your numbers, we find the area to be ...

    A = (1/2) (10²) (2/5π) = 20π

    The area of the sector is 20π square units.
