A landowner digs a 15 meter deep well with a diameter of 2.8 meters. The landowner spreads the dirt dug out of the holds to form a flat platform 31.5 meters by 6 meters. What is the length of the platform?

  • Geometry -

    volume of cylindrical well
    = π(1.4)^ (15) = 29.4π cubic metres.

    confused about the platform.
    When you state the platform as
    "31.5 m by 6 m" , aren't you giving us the length?

    Is the platform a rectangle, where you gave the length and width and we have to find the height ?
