Volumes - Volume of cone = (1/3)πr²h, - Volume of cylinder = πr²H (H = height of cylinder), - Total volume = Volume of cone + Volume of cylinder. Equation for total volume Total volume = 3 × Volume of cone: (1/3)πr²h + πr²H =Read more

    Given:
    – Total volume of solid = 3 × Volume of cone,
    – Height of cone = h.

    Volumes
    – Volume of cone = (1/3)πr²h,
    – Volume of cylinder = πr²H (H = height of cylinder),
    – Total volume = Volume of cone + Volume of cylinder.

    Equation for total volume
    Total volume = 3 × Volume of cone:
    (1/3)πr²h + πr²H = 3 × (1/3)πr²h.

    Simplify:
    πr²H = (3/3)πr²h – (1/3)πr²h,
    πr²H = (2/3)πr²h.

    Cancel πr²:
    H = (2/3)h.

  3. The sphere's volume is 288π cm³. When submerged, it displaces an equal volume of water in the cylinder. Using the formula for the cylinder's volume, πr²h = 288π, and substituting r = 8 cm, we get: 64πh = 288π → h = 288 / 64 = 4.5 cm.
