    complete question:

    Find the missing dimension of the cylinder. Round your answer to the nearest whole number.

    volume = 250 ft³

    diameter = 8 ft

    h = ___ ft

    Answer:

    h ≈ 5 ft

    Step-by-step explanation:

    The volume of the cylinder is given, likewise the diameter of the cylinder. The volume a cylinder can be represented as

    volume = πr²h

    where

    r = radius

    h = height

    we were given the diameter, so we find the radius from it diameter.

    r = d/2

    d = 8 ft

    volume = 250 ft³

    r = 8/2 = 4 ft

    volume = πr²h

    250 = π * 4² * h

    250 = 16πh

    250 = 16 * 22/7 * h

    250 = 352h/7

    cross multiply

    250 * 7 = 352h

    1750 = 352 h

    divide both sides by 352

    h = 1750/352

    h = 4.97159090909

    h ≈ 5 ft

    3ft (to nearest whole number)

    Step-by-step explanation:

    Volume of a cylinder = πr²h

    Where r is the radius

    h is the height

    Given volume = 250ft³

    Since are not given the radius, let's assume the radius of the cylinder to be 5ft

    Substituting this values in the formula to get the height

    250 = π (5) ²h

    250 = 25*3.14*h

    250 = 78.5h

    h = 250/78.5

    h = 3.19

    h is approximately 3ft (to nearest whole number)
