Question

a rectangular piece of paper 71 cm long and 10m wide . a cylinder is formed by rolling the paper along its length , find volume ??​

Answer 1

Volume=355 cm³

Explanation:

I assume it should be 10 cm, not 10 m. If it is 10 m, everything will have to be adjusted.

Circumference = 2
`\pi`r

10=2
`\pi`r

10÷2
`\pi`=r

1.59=r

V=
`\pi`r²h

V=
`\pi`(1.59)(71)

v=355
