    Answer:

    r = 2.25733059

    round to whatever place your teacher wants.

    Step-by-step explanation:

    The formula for volume of a cylinder is

    V=πr^2h

    Plug in what we know

    400 = πr^2(25)

    divide both sides by 25

    16 = π r^2

    divide both sides by π (= 3.14)

    r^2 = 5.0955414

    then take the square root of both sides

    r = 2.25733059

    round to whatever place your teacher wants.

    Kind of wishing the volume was 400π, lol. Would be easier to solve.

    LMK if you have questions.
