    Answer:

    27.5\  m

    Explanation:

    As we know that volume of cylinder is

    v=\pi r^{2} *h

    Where v=volume , h= height or thickness and r= radius

    Here,

    v= 10 m ,\  diameter= 10, \ r=\frac{diameter}{2} \ r=\frac{10}{2}\\ r=5

    Putting these values in the previous equation , we get

    10\ = \frac{22}{7} *5 *5*h\\ 14\ =\ 110*h\\h=\frac{110}{14} \\h=\frac{55}{2} \\\\h=27.5\  m

    Therefore thickness is 27.5 m
