    The answer to your question is r = 5 ft

    Step-by-step explanation:

    Data

    Volume = V = 785 ft³

    height = h = 10 ft

    radius = r = ?

    pi = 3.14

    Formula

    Volume of a cylinder = πr²h

    -Substitution

    785 = (3.14) r² (10)

    -Solve for r²

    r² = 785 / (3.14) (10)

    -Simplification

    r² = 785 / 31.4

    r² = 25

    -Result

    r = 5 ft
