Answer:
Radius is10. 5 mm.
Volume is 3463cubic meter.
Step-by-step explanation:
The piece of paper is rolled along the length to form a cylinder.
Therefore the perimeter of the base circle is equal to the length of the paper.
Also the length of the cylinder is equal to width of the paper.
Let the radius of the base circle be Ready.
Therefore,
2πR = 66
R=(66/2π)
R=10.5mm.
Volume of the cylinder is equal to,
=π×R^2× h.
=π×10.5×10.5×10
=3463cubic meter.
