    Answer:

    area of cross section of cylinder is  inch²

    Step-by-step explanation:

    Given : Cylinder is 7 inch tall and has a volume of inches³.

    We have to find the area of cross section of cylinder.

    Area of cross section of cylinder =

    To find the cross section first find radius.

    Given Volume of cylinder = inches³

    Also , Volume of cylinder =

    Thus,

    Divide both side by 7, we get,

    On simplifying , we get,

    Since, radius has to be positive, thus neglecting negative term.

    Thus, radius of cylinder = 3 inch

    Thus, area of cross section of cylinder =

    area of cross section of cylinder =

    Thus, area of cross section of cylinder is  inch²

    Step-by-step explanation:
