    Answer:

    • A. 15 pi square meters

    Step-by-step explanation:

    Volume of the cylinder:

    • V = bh

    Given

    • V = 315 pi m³
    • h = 21 m
    • b = ?

    From the volume formula we get:

    • b = V/h
    • b = 315 pi m³ / 21 m = 15 pi m²

    Correct option is A

    Answer:

    A. 15 pi square meters

    Step-by-step explanation:

    Formula for cylinder volume:

    • V = bh

    What we know:

    1. V = 315 pi m³

    2. h = 21 m

    3. b = ?

    b = V/h

    So, 315 pi m³ ÷ 21 m = 15 pi m²

    Our answer is 15 pi square meters (15 pi m²)
