Answer:

[tex]27.5\ m[/tex]

Explanation:

As we know that volume of cylinder is

[tex]v=\pi r^{2} *h[/tex]

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

Here,

[tex]v= 10 m ,\ diameter= 10, \ r=\frac{diameter}{2} \ r=\frac{10}{2}\\ r=5[/tex]

Putting these values in the previous equation , we get

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

Therefore thickness is 27.5 m
