volume of cylinder = πr^2h
= now paper width = circumference =22cm
2πr=22
πr= 11
r = (11×7)/22
r= 3.5 cm
volume =22/7 × 3.5×3.5×20
= 22×0.5 ×3.5 ×20
= 22× 5× 7
= 110×7
=770 cm^2
= now paper width = circumference =22cm
2πr=22
πr= 11
r = (11×7)/22
r= 3.5 cm
volume =22/7 × 3.5×3.5×20
= 22×0.5 ×3.5 ×20
= 22× 5× 7
= 110×7
=770 cm^2
