if the cylinder is rolled along its breath it's breadth becomes height of the cylinder and the length becomes the circumference of the circle of cylinder
so, circumference=2πr
33=2×22/7×r
r=33×7/22×2
r= 10.5cm
so, circumference=2πr
33=2×22/7×r
r=33×7/22×2
r= 10.5cm

breadth of rectangular = circumference of circle
18=2πr
18=2 * 22/7 * r
18*7/44=r
r=2.86cm
